In all seriousness, if a man puts a GLOCK 21 in his mouth and pulls the trigger, is it GLOCK that "killed him"?

If I take my car and intentionally drive into the ocean, I expect it to continue until the engine dies, and then I do shortly after. Why should machines start prohibiting me from doing stupid things, if I want to do them? I think Isaac Asimov wrote a parable about such a future.
