That said, I can understand what fylimar is saying above, which is that the search for power often *feels* like the evil choice, and we're all conditioned in some way to expect a punishment for going that route. But that's a built in morality thing we've all gotten used to. It begins to fall apart when examined closely.
In this game, the approach is not typical. To win, you have to sacrifice a portion of yourself. You have to be reborn, forfeiting your soul and appearance. Doing so happens over a long and slippery slope as you are eventually forced to come to terms with the reality of what it will take to win.
"But I want to win without that sacrifice!" --sure, of course you do. But that's not the way it is. It's not your fault that the world is wicked.
The problem is that I "want" to roleplay this particular angle, but the game doesn't really provide the right context, at least for a very large portion of the game. I can pretend that I'm sacrificing something, but I can also pretend that certain parts of the game are better written than they actually are, and that gets us nowhere.
