Where do we go when we die and are you afraid?

[Duty]

RE murder - there's this thing called "the law" which is a major deterrent for many - 35 years in prison etc. Also empathy, for victims, their families etc, as has previously been mentioned in this thread. Also wishing to maintain self esteem through not being a murderer. Other atheistic reasons too no doubt, as if those already mentioned weren't enough. No need for afterlife incentives whatsoever.
