What if Madra Uchiha wasn't evil.

What if Madra Uchiha wasn't want to launch infinite tsukuyomi?

Then we wouldn't have much of a show...

Then I guess he would have been a good guy.

I'm not really sure. It seems like every anime needs villains of some kind (or at least the ones I watch do), but sometimes there can be reasons for their motives that can be relatable or something in their history to give them that sympathy for the devil kind of feeling. I think Madara Uchiha was a pretty imposing and capable villain, but if he was a good guy there still would've been some other villain to take his place as the antagonist(or one of them).

It would be pretty boring without the bad guys in a show. The plot of the show would have been mostly pointless without that. I guess another guy could have been the evil guy but it worked better with it being Madara.

Tsunade might have made a pretty good villain...
