Nobody in his right mind will suggest guns are sentient or have decision powers. It's more of a matter of convenience. If I for a number of reasons go berserk and decide to murder my family and a few neighbours too and shoot myself in the end, it will be much more expedient if I have easy access to a gun of a decent calibre and sufficient ammunition; I will be able to do much more limited damage if all I can use is a bread knife.

How big would the butcher's bill have been if the Columbine boys had been able to procure only two nail clippers, a swiss pocket knife and a crowbar?
