And you can use hammers to brutally murder people as well as to drive in nails. You can use a screwdriver to grievously wound someone besides using it to repair your glasses. The fact that a tool can be used for bad things does not negate the good things it can be used for. Nor does it mean that the maker is responsible if someone chooses to use it for bad things.

FWIW the vast majority of guns sold to civilians never get discharged at anything other than pieces of paper.

(And quite a few never get used at all - "safe queen" is a well-established term for a reason.)
