So, it's more likely that someone will tell you a lie than the truth. Evil wins. Good loses. — TheMadFool
As you very aptly pointed out, this statement is is evil if you superimpose a morality on it, namely, "lying is bad".
However, morality is a "moving target". It is not a fixed entity and not fixed quality. Some may argue, that morality is completely arbitrary.
I shan't argue that. I will accept that lying is bad.
But I shall expand this acceptance of standards by saying that what is bad for one party, may not be bad for another party. Lying is a superimposed morality, that is, it is dictated by society, by authority. Lying is not an innately moral evil. If lying was an innate moral command, nobody would lie. We lie, because the mechanism of the lying process assumes that advantage is gained, and the lie shall go undiscovered.
We all lie. Why do we lie? Many reasons for it, and I shan't go into that. My point is that all interpersonal evil, morally judged or not, is evil for one party, and good for the other. Be it senseless Sadism that makes one lie, or a conniving attempt for undue advantage, or stupidity, all lies favour one party, and work toward the detriment of the other party.
I reject therefore the notion that all lies are always evil for all concerned. First of all, I reject that lying (not telling the truth on purpose) is immoral. It is immoral in some interpersonal sense of judgement, but in and by itself lying is not immoral, and many examples are extant to prove that exceptions to "all lies are evil" exist. Second of all, if a lie is evil, then it is necessarily good for some other party, at the same time. Lies can't be all bad (evl) for all parties at any given time.
This can be shown to be similarly true for the value couplets of (love, hate), (truth, lies), (kindness, meanness), (selfless, selfish), etc.
Therefore good will not be defeated by evil via acting immorally.
Now, you may talk about fair play, ethical expectations, and telling the truth. But to be fair, you must admit that telling the truth hurts the teller once in a while. You say telling lies hurts someone (the teller or the hearer of the lie). One is ethical, the other, is un-. So if they both hurt someone, and favour someone else, then I don't see how you can declare that lying causes more hurt than telling the truth.
