I agree with you but he also hasn ' t been fired yet , <| sep |> Same reason most people don ' t kill themselves . Our instinct to survive and living a calm life without dangers helps us to survive and gives us the ability to procreate . It also helps that we need other people to feed ourselves and live that safe life . Murdering is not something that is mostly beneficial to an individual of a species , although sometimes necessary . If you really have to murder in order to complete your life and that of others , you will have to , and I see no reason to believe eternal damnation is waiting because of that . If you had no good reason to kill , people will make your life a lot harder . The question you should really askWhy should I kill other people ? Have no reason ? You don ' t . Have a reason ? You probably won ' t because of the consequences in reality . Or as uAnurse 1701 said Because being an asshole isn ' t good for prosocial primates
