Current Affairs: Is It Wrong to Piss on the Dead?

Is it just me or is there anyone else who feels it suggests warped moral standards that pissing on people you killed is seen as despicable, but the killing itself is not? It seems to me that's getting things backwards. I'd rather be pissed on than killed, and if I'm already dead when I'm pissed on, hey, at least I won't mind. I'm not saying pissing on victims suggests a noble mind on the part of the pisser, but that kind of behaviour is really one of my last concerns when it comes to war.
