I would kill only for the world to benefit, I would off corrupt government officials, I would kill world leaders that are trying to cause wars(Iran, Pakistan, maybe even my own country; America), I would send in death threats to halt all wars, or else every leader of every country dies and the world goes into panic, then, only then, would I actually start killing people that escaped justice, such as OJ and Michael Jackson, people like them. Than, after all that is done and taken care of, I would start ridding the world of criminals(Only ones who committed a serious crime; such as murder, rape, kidnapping, molestation, cannibalism, etc). IF, however, anyone did get in my way, I would evade them as long as possible, give them multiple warnings then kill them.
