Nothing "deters" these sorts of crimes per se; they are, by definition, acts that are only committed by people with screws loose (not talking about petty B.S. but serious offenses like robbery, rape, murder, etc). They will not be deterred because they don't have the same value system (or any at all). The gun is not invalidated because they are ineffective at deterring crime, they are validated precisely because crime cannot be deterred.
You wouldn't drive an unsafe car because of the risk to others, but because of the risk to yourself. The instinct of self-preservation and the simple ability to observe the world around us is all the reason anyone needs to own a firearm.
