I would agree wih all of those except for Itachi and Madara. Itachi was never evil in the first place. Madara is still pretty evil and I am willing to bet that he's gonna do something to take over Obitio's spot in the upcoming manga's. I just hope he doesn't have some "change of heart" that would be lame.
Itachi was "misunderstood" because he eventually was exposed to have done everything for the sake of his brother/village.
Madara was misunderstood because he was going to be a good guy but his brother died.

:/ Everyone was pretty "evil"(lol shonen) for their presence initially, but the problem is that towards their inevitable defeat they all get some sort of soppy flashback and become "misunderstood".
