The Dangers of Killing People

I think it's a bad idea for governments to kill people. 270 million people got murdered by their own government last century. We don't want to kill good people, just bad people, but who decides? That's my problem with it. Once you open that Pandora's box and you start being okay with killing people like this, well, then maybe you'd be okay with killed people like this over here. So I would rather pony up some money and pay for someone who maybe should be dead to continue to be alive.
