When animals get rabies, they become a danger to both themselves and people, and and they are killed, for safety reasons. There is no "hatred" involved when we euthanize a rabid animal. A person like Osama Bin Laden may as well be a rabid wild animal (only OBL is far more cunning, far more dangerous, and just as untreatable and incorrigable), and sentencing such a being to death is not only entirely appropirate, but also the morally correct thing to do.
Well that's been my point all along, although I wouldn't go as far as to say "morally correct". When we're dealing with a situation like this, it's important that we be pure of intention. The problem is too many people are interjecting themselves into the situation and making it a matter of hatred and vengance. What's more, these are people who aren't even involved in what's going on, they're just sitting in their house going "kill kill kill, he deserves to die! Oops, Friends is on now, gotta go". Tell me that's not repugnant, we should be capable of a little more than that. What purpose does any of this malice serve? It's just destructive, we need to come full circle and realize that we don't have the right to dictate these things, or to put ourselves on a moral high horse. At the same time we do have a right to protect our way of life, and that's all this really needs to be.
