Somehow I don't get the point of yours. So Sasuke shouldn't be hated just because he's strong? How does strenght affect whether or not you hate him? That is of course, assuming you can hate a Manga Character.
Last time I checked, Hidan was strong too and he was hated. Same goes for pretty much all Akatsuki members. They were villains after all, weren't they? And I'm not talking plot wise, but structure wise. Hating Sasuke has nothing to do with his Strenght. People who said that or something similar are definitely stupid. Hating Sasuke has to do with his personality, his mentality. The way he behaves, the decisions he makes and the effect those decisions have. He's strong and cool, I give him that. But he's a douche. A scumbag. Self centered, arrogant, preposterous, and we can go on and on.
You may try to defend him beause of what he's gone through, but I still don't buy it. Nagato went through even worse shit, and Naruto didn't have to talk to him or chase after him more than once to make him think through... Which also makes Sasuke either too proud on himself or just plain stupid. The fact that he's attractive because of his, say, aura of darkness... Well, that's just relative. I myself think his darkness shit is kinda cool, actually, but the way he represents Darkness makes Darkness look like it should be erased. Wrong. Darkness needs to exist for there to be light. I think a better representation of Darkness wouid be the Root. At least they strive for peace. Not some half assed revenge that has been in the series for longer than enough.
Please save your arguments about how strong Sasuke is. I know how strong he is better than most. He's just cruel and hopeless in terms of character. Think of Yagami Light. I like him, but he got his ass killed. And if Sasuke keeps going on this way, he will be no different. A pitiful man who thought himself better than the rest, and paid the price for his arrogance.
