Statistics brother. The vast majority of people will never murder/kill anyone. The problem here is that any one person that kills people can wreck a lot of havoc, and we spend massive amounts of law enforcement resources to stop and catch people that do these kinds of things. Intelligence little to do with murdering/not murdering, hell, intelligence typically allows people to get away with it. For example instead of just murdering someone, you setup a company to extract resources and murder the natives in mass and it's just part of doing business.
