Does that make Tobirama a villain as well? He isolated the Uchiha because he feared they're Cursed of Hatred would harm the village. He thought what he did was right.
" He never was for destroying Konoha "
That's a tough one but I think tobimara is still a good guy with some flaws but never really acted on them that much whereas Danzo has shown to act on his hatred for uchiha in asking the third hokage to wipe them out. It's interesting because I could see it going both ways I guess
That doesn't make him a villain. That makes him a douche. He is willing to risk lives to become Hokage.
Tobirama is not exactly like Danzo.
Yeah, then later risk his life after relizing the understanding of what it means to be Hokage.
He would have died regardless. Choosing a draw when your death is imminent is not good nor evil, courageous, nor cowardly.
It was game over for him, so what path he chose then didn't even matter. He knew he was going to die, so that barely counts. What matters isn't how you die, but how you live. How you lived defines who you are. Choosing a new path once you die like Danzo is just saving face when you realize nothing matters at that point.
He is not a protagonist, he's a challenge for the protagonist and creates conflict, making him a villain. If he fits anti hero then so does Obito and Madara.
