"I don't kill people because I'd get caught" is probably true for most people.

If you lived in a society where killing didn't tend to be punished, you'd probably kill. Because if you didn't you'd be dead. Don't underestimate people's tendency to adapt to their environments.

I get what you are saying, but I think if you look at it in the big picture, sites which require real names (and sites that otherwise reward you for gaining a positive reputation over the long term) tend not to degenerate into cesspools of ugliness. It may be partly because the non-civil go elsewhere, but I think it also is because it encourages civility from those who are there.
