C.S. Lewis on Jesus Gregory,
It's fascinating to me that you look at Lewis's 3 possible categories. If you haven't read Mere Christianity by Lewis, I certainly recommend it. Especially since you are provided the necessary underpinnings of the Christian religion. Your question, "Is Jesus evil" I would argue is opposed to virtue and offers that he is not God, (if God is good) or that God is evil. The latter is consistent with Christ's claim that "I and the Father are one". Assuming then, the existence of God, which you seem to imply, I would argue further that God is not evil. This of course is proposed by the natural theology of humanity. We as a collective argue that the Good, True and Beautiful are something to imitate/aspire to. Not Evil, Falsehood, and Ugliness. So then, if Jesus is God then he is good by nature of his deity.
As for the scriptural quotes you mentioned, there are far better scholars than myself to consider. However, my simple understanding of these passages is that they emphasize the call to discipleship, by way of hyperbole. You will see this literary device in many New Testament passages, and I do not blame you for being mistaken by them.
