Then tell me what responsibility a hero has if they keep defeating the same villain, only to let them rebuild and play out their act of tyranny?

[ if she could ask what it is that sonic does that is a "responsibility" on his part, there's no answer that could satisfy her. ]

There's just some villains that need to be killed, and some heroes that should be taken out because to me, it sounds like they don't care what the consequences are! Or they don't have any at all.
