Look at the pansy that is Obito. Seriously. Rouge has the balls to kill anyone to get to the top. Obito? -vomits a bit- You want to talk weak? He's changing his story. "I know why you killed Rin but you're still a bastard." is the current itteration of his BS. First thing a Shinobi should learn is this: "Life sucks then you die. Don't get too attached to your squad, they'll likely be dead soon anyway." Hell, Kakashi knew that but Talk no Jutsu changed his mind.

Rouge's logic? "I want to rule."

Obito Logic? "My girlfriend (who honestly didn't have any feelings for me) is dead!"

See, that's the difference. Both are wants, yes, but...Rouge has the drive to achieve his goals and to Hell with anyone. Obito's logic is the wimpy way out. He wants to control reality itself so that he doesn't have to EARN anything.

In short, one thought makes you at least a tolerable bad guy, the other makes you Edward Cullen with eye powers.
