The moral flaw in that sort of 'argument' Prism is that it is essentially saying that others are evil, so we should seek to be as evil as them.

In contrast, rational people try their best to uphold the law, whether it's God's law or a law of mankind, and to live as honorable people.

That's what sets mankind above animals - an understanding of what is right and what is wrong, and even if others are doing wrong, they will strive to do what's right.

Obviously this isn't a view shared by everyone.
