Uchiha Logic
Madara: Wants to come back from the dead (I mean why man your dead what do you care), just so he can enforce his twisted world peace on others
Obito: Starts a world war because a girl who never showed any romantic feelings for him died, attacks his own village, attacks a pregnant kushina, tries to kill a baby Naruto, and his master. He thinks by saying to Naruto that "your father was pathetic and couldn't save your mother," that Naruto would follow him oii wasn't it because of you that he ain't got no parents in the first place.
Sasuke: He left the village because he wanted to kill his brother, goes to a orochimaru for power, kills him (or so we thought), goes to kill itachi (itachi dies), obito starts to tell him about the truth, he now wants to destroy konoha. Why do you want to destroy konoha, when 97% of the population had nothing to do with it. I mean isn't he dead cause of you kill yourself fool. he has the nerve to say to the Hokages that if your answer is not to my liking that I will destroy konoha (Like he could), hashirama would kill him, then he says he wants hokage by killing Naruto,the bijuu's, and the past kage, only to fail miserably.
Itachi is the only good one in my opinion and sarada is a child no sane person would take her childish thoughts seriously.
