You have to admit that "the death toll could have been higher" doesn't exactly communicate grief for the dead, and conservatives here and elsewhere have used that thinking to justify the casualties.
But you're right. He said you were without compassion, so you did the same to him. Fair's fair: an eye for an eye. ...That's from the Old Testament, isn't it?

Not trying to be snarky here. But really, think about Christianity, please. I don't even believe in God in any conventional way that even I recognize anymore, but the older I get, the more of a hold it gets. Which Code do you want?
