Let's say you do not want to be murdered

Then it would make sense to want to live in a community where murderers are imprisoned or executed to prevent them from committing more murders so that there are less likely to be people who would murder you

But living in such a community would mean that if you murder someone you would be imprisoned or executed

The laws of physics result in a reality of do not murder if you do not want certain things to happen to you without a presupposed moral system
