Terrorism's Mortalty

So apparently Osama Bin Laden has been killed. To be honest, I discovered this fact through the impossibly quick network facebook has generated. I could not get over just how many people were status updating with the news of his death, but not only that. They were also expressing their ecstatic joy about the situation and thanking god or whomever and whatever as well as showing their utmost gratitude. For a death.

How is that okay?
Alright, I understand that he's a bad person and I get that what he has done was very very horrible. But, I cease to be amazed at the fact that people are actually more than rejoicing in a person's death. I am blown away by how so much happiness can be drawn from death, even if the person was a not so great guy. When has it ever been okay to be happy about someone's death? It's okay to be relieved and feel liberated, and maybe a little reluctant joy, but really? People are overtly excited and thrilled about this 'accomplishment'. But if you look at it from a way outside perspective, maybe these too enthralled emotions are unwarranted. Death is still something that should not bring so much happiness. Where's the karmic factor? Death, regardless of who, is still considered to be an ultimate tragedy in life right? Where do we draw the line?

But that's just me, I always feel bad for the underdog. I always feel bad for the bad guy and his conscience (whether it exists or not) more than the victims involved, even though it's all still a great grave loss. Yeah, don't ask me about my empathy rules, I don't get it myself.
We should all just hope that there won't be any sort of retaliation resulting from this event.
