My advice is, don't rob.
Anyways, if you still decide to do so:
Robbing is a felony, so is murdering someone. If you decide to kill him, because he might report you to the police, you have to deal with being wanted. You receive a more severe punishment for murdering than just robbing. An alternative to killing, would be to ditch him somewhere, and find an original method to get away with it. Just shooting him is too mainstream. For example, knocking him out and calling the EMS afterwards would be an option.
