Since they are always jumping at any chance to be violent, I wouldn't put it past them. They likely would think that where others have died, they will survive...Originally Posted by David75
We know at least the weaker ones know true friendship. But are they even alive or capable of defeating the Novas after graduation? The stronger ones, based on what we have seen, seem more like bosses surrounded by sycophants or temporary allies brought together by a common, transient goal (like eliminating somebody who could pose a threat in the future). Unlike many shounen shows would have you believe, becoming evil doesn't make you a friend of another evil person. Of course we have also non-evil individuals who are simply otherwise troubled, self-absorbed - and violent.
