You've given an inanimate object the ability to kill regardless of intent, therefore, I stated any object can kill to which you then step back and state that this inanimate object now has a consciousness and knows it's own intentions. That of course is ludicrous... the gun does not kill, nor does any inanimate object have a conscious or an intent. ALL of those things come from the person use the object, be it a pencil or a gun. Both a pencil and a gun can kill - it's means or intent of manufacture is irrelevant. Intent and consciousness are human qualities, therefore:
Guns do not kill, people kill. People kill other people in a myriad of ways as you well know. Stop projecting intent and consciousness on inanimate objects and start projecting intent where it belongs, with the human.
