Interesting, I didn't know that. I don't know how the comics handle these subjects, but I think the most annoying part of basically all the marvel movies is the way they bring up an interesting moral conundrum only to completely abandon the idea once the reason for characters to fight is set up.
Thanos has a point? Can't have that, he's the bad guy! Let's make him do the most evil thing he possibly could with that power so you never need to think about it again. What's that, Civil War has interesting points on both sides? That's nice honey, anyway, Tony and Cap are going to beat each other up now and we're never going to mention it again.
...yours can't?
