Who's Responsible for Death?

I've just read an article on Troy Davis, a man who has escaped the lethal injection narrowly several times, but still remains on Death Row due to him being black. After reading this I was just so angry and sick that after all this time WE'RE STILL THERE. We're STILL at that point where the color of your skin can determine what kind of a person you are. It is 2011! And we still judge each other by unimportant factors. No matter if your white, black, Hispanic, gay, lesbian, poor, rich, you shouldn't have to die because someone didn't like your uncontrollable circumstance. They should dislike you for you actions or your character. This man has had serious doubts on whether he's innocent or not and most of the evidence or lack there of tend to point to innocent yet he could be dead soon. Just because he's black. Tell me that's fair. Please explain to me how that is the epitomy of legal justice. Please. Politicians in favor of the death penalty use the argument that the injection should be left for the "worst of the worst". But, is any human even entitled to decide the fate of another? You can bring up Osama Bin Laden and Sadamn Hussein, tell me there were monsters who killed masses of people. That's true. But, we as a people turned into monsters when we decided to CELEBRATE death. Cheer. Flood the streets and set off fireworks. Because someone died. To me it's as if your close enemy died and you popped a bottle of champagne. Would you actually do that if you actually knew the person, even if only as a nemessis or hurtful being? Murder is a hard thing to justify, folks. Wars are even harder. In the end, does I really benefit people? Yeah, maybe, centuries from now when they're read in a history book. But now? We just get some land, "pride", and a lot of dead bodies. Does it really work to get "an eye for an eye"? Especially when a lot of times it's based on the most senseless "principles" or ideas? Please explain your rational to me and I'll gladly listen. But, unless someone can make sense of all this, I'll just sit back and wonder why.
