Let's get the story straight with Nietzsche, the only Hero to Nietzsche was the tragic hero. He repudiates Carlyle's Hero cult. Further still, Nietzsche doesn't glorify crime for the sake of crime, and thirdly, the Aristocratic and Slave are Typologies not Hierarchies.
But more importantly what is missed here is that Nietzsche advocates for all of human nature, and details that the systematic killing off of the Dionysian instincts in man is what has made man sick through cherishing cowardly compromise and lazy peace.
We can see from Nietzsche's Birth of Tragedy onward that Nietzsche has this idea of the dual orbit of opposites that overcomes each other in their opposite inciting each other to higher and higher births, reconciling the worst of the destructive properties of both forces in a dual orbit over a mutual bridging.
This becomes the very framework of Nietzsche's philosophy.
heterogeneous tendencies run parallel to each other, for the most part openly at variance, and continually inciting each other to new and more powerful births, to perpetuate in them the strife of this antithesis, which is but seemingly bridged over by their mutual term...
the Delphic god [(Apollo)], by a seasonably effected reconciliation, was now contented with taking the destructive arms from the hands of his powerful antagonist. This reconciliation marks the most important moment in the history of the Greek cult: wherever we turn our eyes we may observe the revolutions resulting from this event. It was the reconciliation of two antagonists, with the sharp demarcation of the boundary-lines to be thenceforth observed by each — Nietzsche, Birth of Tragedy
This is how Nietzsche details the height of Greek culture, through equal parts Apollonian and Dionysian forces. And the Height of the Human in general...
After Nietzsche's early experimental writing phase, Nietzsche sets up the Framework of his philosophy in this very manner which he details in
Ecce Homo:
BEYOND GOOD AND EVIL:"THE PRELUDE TO A PHILOSOPHY OF THE FUTURE"
1
My work for the years that followed was prescribed as distinctly as possible. Now that the yea-saying part of my life-task was accomplished there came the turn of the negative portion, both in word and deed: the transvaluation of all values that had existed hitherto, the great war,—the conjuring-up of the day when the fatal outcome of the struggle would be decided. Meanwhile, I had slowly to look about me for my peers, for those who, out of strength, would proffer me a helping hand in my work of destruction. From that time onward, all my writings are so much bait: maybe I understand as much about fishing as most people? If nothing was caught, it was not I who was at fault There were no fish to come and bite. — Nietzsche, Ecce Homo
In Nietzsche's yea-saying period he attempts to make the penultimate in yea-saying... In Nietzsche's nay-saying period he attempts to create the penultimate in nay-saying. Thus Spoke Zarathustra is the Chord that intertwines both periods into a Dionysian Dithyramb.
We can see Nietzsche detail the typeology of the higher and lower types in Gay Science, Thus Spoke Zarathustra, Beyond Good and Evil Genealogy of Morals, and more...
The ignoble nature is distinguished by the fact that it keeps its advantage steadily in view, and that this thought of the end and advantage is even stronger than its strongest impulse: not to be tempted to inexpedient activities by its impulses—that is its wisdom and inspiration. In comparison with the ignoble nature the higher nature is more irrational:—for the noble, magnanimous, and self-sacrificing person succumbs in fact to his impulses, and in his best moments his reason lapses altogether. An animal, which at the risk of life protects its young, or in the pairing season follows the female where it meets with death, does not think of the risk and the death [>>this is why mankind is sickened on lazy peace and cowardly compromise too afraid of the risks it takes to discover something new, to be that bridge to the future, to be that bridge to strange new vista<<]; its reason pauses likewise, because its delight in its young, or in the female, and the fear of being deprived of this delight, dominate it exclusively; it becomes stupider than at other times, like the noble and magnanimous person. — Nietzsche, Gay Science
Continuing with these quotes we come to 260 in BGE where we can see Nietzsche detailing the two types of morality that rises from the two different types of man, but also that the higher and mixed civilizations arise from an attempt of reconciliation between the two types...
there's that bridging through reconciliation again...
In a tour through the many finer and coarser moralities which have hitherto prevailed or still prevail on the earth, I found certain traits recurring regularly together, and connected with one another, until finally two primary types revealed themselves to me, and a radical distinction was brought to light. There is MASTER-MORALITY and SLAVE-MORALITY,—I would at once add, however, that in all higher and mixed civilizations, there are also attempts at the reconciliation of the two moralities, but one finds still oftener the confusion and mutual misunderstanding of them, indeed sometimes their close juxtaposition—even in the same man, within one soul.... The noble type of man separates from himself the beings in whom the opposite of this exalted, proud disposition displays itself he despises them. Let it at once be noted that in this first kind of morality the antithesis "good" and "bad" means practically the same as "noble" and "despicable",—the antithesis "good" and "EVIL" is of a different origin. The cowardly, the timid, the insignificant, and those thinking merely of narrow utility are despised; moreover, also, the distrustful, with their constrained glances, the self-abasing, the dog-like kind of men who let themselves be abused, the mendicant flatterers, and above all the liars:—it is a fundamental belief of all aristocrats that the common people are untruthful. "We truthful ones"—the nobility in ancient Greece called themselves. It is obvious that everywhere the designations of moral value were at first applied to MEN; and were only derivatively and at a later period applied to ACTIONS; it is a gross mistake, therefore, when historians of morals start with questions like, "Why have sympathetic actions been praised?" The noble type of man regards HIMSELF as a determiner of values; he does not require to be approved of; he passes the judgment: "What is injurious to me is injurious in itself;" he knows that it is he himself only who confers honour on things; he is a CREATOR OF VALUES. — Nietzsche, Beyond Good and Evil
Below from Genealogy 10, we can see that Nietzsche details yet again that the Noble type of man maintains a BRIDGE to his love... while the weak cherish the onslaught of their enemies.
...the vindictive hatred and revengefulness of the weak in onslaughts on their enemies....
What respect for his enemies is found, forsooth, in an aristocratic man—and such a reverence is already a bridge to love! He insists on having his enemy to himself as his distinction. He tolerates no other enemy but a man in whose character there is nothing to despise and much to honour! On the other hand, imagine the "enemy" as the resentful man conceives him—and it is here exactly that we see his work, his creativeness; he has conceived "the evil enemy," the "evil one," and indeed that is the root idea from which he now evolves as a contrasting and corresponding figure a "good one," himself—his very self!
11
The method of this man is quite contrary to that of the aristocratic man, who conceives the root idea "good" spontaneously and straight away, that is to say, out of himself, and from that material then creates for himself a concept of "bad"! This "bad" of aristocratic origin and that "evil" out of the cauldron of unsatisfied hatred — Nietzsche, Genealogy of Morals
The word "Superman," which designates a type of man that would be one of nature's rarest and luckiest strokes, as opposed to "modern" men, to "good" men, to Christians and other Nihilists — Nietzsche, Ecce Homo
For Nietzsche the Highest type of man comes from acknowledging all of their human nature, not trying to kill off half of it, which is the aim of morality... to kill off half of our human nature.
This is why Zarathustra doesn't come down from the mountain and begin murdering his enemies... because he maintains that bridge to love for a possible reconciliation with his enemies. And it is in this that Nietzsche only ever details the Superman becoming a reality...
See how Zarathustra goes down from the mountain and speaks the kindest words to every one! See with what delicate fingers he touches his very adversaries, the priests, and how he suffers with them from themselves! Here, at every moment, man is overcome, and the concept "Superman" becomes the greatest reality,—out of sight, almost far away beneath him, lies all that which heretofore has been called great in man. — Nietzsche, Ecce Homo
Why? Because as Nietzsche details in Thus Spoke Zarathustra.
What is great in man is that he is a bridge and not a goal: what is lovable in man is that he is an OVER-GOING and a DOWN-GOING. — Zarathustra
It’s quite obvious this Ishay Landa doesn't really have a deep grasp on Nietzsche's works.
So as we can see Nietzsche creates two distinct opposing periods because both of these periods are the totality of Nietzsche himself... as Nietzsche details in BGE 2 that two opposing forces are intertwined with each other through a chord that ties them together, making them all fundamentally one in the same as whatever creates the two values... these two values do not exist as an antithesis of values, one value grows out of the other value.
We can see this notion in the Gospels of The Bible, even with John 15:5 "I am the vine. You are the branches: he that abideth in me, and I in him, the same beareth much fruit: for without me you can do nothing."
And just like John 15:5 the dual orbit is nothing without the other to overcome in their opposite and insite each other to higher and higher births. The branches of Nietzsche's works are those two Yea-saying and Nay-saying periods, the Vine that weaves them all together is his Thus Spoke Zarathustra. Just as MAN is the ROPE between the ANIMAL and SUPERMAN.
The Gospels is one of the greatest influences on Nietzsche's philosophy. It is where he gathers his concept of the Overman and Amor Fati from. From the example of Jesus Christ and his psychology of The Glad Tidings that Nietzsche details in AC 33 and AC 39.
