Why? They suppose to be "better" and uphold some rules that only make them lose and people die. Ethics when people are being hurt badly is a myth. You guys would literally okay the the Holocaust today. "We can't do anything because you have obey laws and we can't go into their country. Heroes don't break laws. You need congress and the UN to approve helping people. Heck million Muslims are sitting in camps in China but hey you know Heroes have ethics so those people have to wait around die and live miserable lives. Running to "ethics" in these complex topics is wrong. Understanding how the world is responding to situation in the best manner that save people through whatever method is the best way to be "a hero". Yes that means adapting the tactics of success and using it against your enemies.
