the question here is, Is Madara Uchiha truly evil?
If you take in consideration of everythings hes done It seems so but look closer.
First his brother whom he had promised to protect with his life died willing for his brother. ( I believe this due to recent chapters) (he also already lost 3 brothers when he was younger)
His reason for betraying konoha was because he felt that the Uchiha were being overruled by the senju (completely true)
After finally deciding to betray konoha The entire uchiha clan betrayed him and sided with the senju.
years After that they decided to plan a coup d'tat which caused them to be wiped out entirely by there soul and prodigy Itachi uchiha with the assistance of obito uchiha (whom only did it to help madara get his revenge for them betraying him)
He "died" at the hands of his best friend hashirama senju whom of which he has been sorta of in a gai - kakashi relationship with.
Then he gave is eyes to a young child (nagato) so that he could be later revived (via rinne tensei) by nagato.
Not to mention that he had obito form the akatuski with nagato to gather all the bijuu and revive the juubi.
Then he was to be revived by nagato and become the jinchuriki for the juubi and cast Infinite tsukuyomi on the moon casting a genjutsu on the entire world.
but in reality the moons eye plan isn't evil in its self look what zetsu says right here:
He says "He (madara) wants to get rid of all the bad things in the world and run away to a dreamland full of good things. he then says In a dream you can do whatever you want... Even revive the dead (Izuna)"
so Basically Madara's Not evil he just wants everyone to be happy.
