Will humanity ever get the point of not murdering one another and why?

I don’t think so. It’s in our nature. Even if, say, we reach global peace and there are no more wars, there is just this feeling sometimes when someone angers you so much that you want to kill them. Most modern day people can keep that in check but there are some that don’t. Also I think euthanasia should be legal everywhere. After all you’re helping someone by putting them out of their misery.
