To be honest, I have thought about this.

I do have a list of people (not a long one) who I'd like to kill off without consequence but when it came down to it, I would feel too awful about doing it. I hate to admit that, but I would feel awful. Sure, I'd love to stab certain people in the face but when it came to pull the trigger (of sorts) I would chicken out and hide it in my room. If I tossed it and someone found it (like someone who may not like me) then I'd never sleep a wink. So I'd keep it if for the fact that I'd feel safer knowing I had it and someone else didn't. 

Though there's the chance of me coming home in a pissy mood and using it when I'm in a rage but...I'd like to give more thought to using it. Killing politicians or annoys celebrities wouldn't probably do much help, create more of a mess I think.
