I don't really think about the topic of ethics/morals enough to have a very complex viewpoint on it. I think they're "useful" and "important," and I think people who believe otherwise (if they exist-- I have no idea, considering that I seriously have just avoided this sort of discussion altogether in the past) are silly. I can see where certain systems of ethics/morals can be flawed or harmful to a society, but then it's just a matter of fixing those imperfections as we find them.
Kind of a vague viewpoint, but that's all I really have.
