Does a child being stabbed in the face make knives evil? Or a child being crushed by a car make vehicles evil? Guns are inanimate objects and I don't really understand the desire to assign them attributes like "evil." There are absolutely evil people who use guns to do evil things, but the same can be said for many other objects.
This is a twisted line of argument and you know it. Of course I don't think guns are literally animated by evil spirits or something similar. It's an easily understood metaphor that nearly anyone would recognize and understand, are you claiming you don't?
It's also wack to pretend that guns are just one kind among all the objects that can exist and not special in any particular way. Again it's not likely that you believe that. Guns are set aside in that they are designed exclusively for one person to cause misery and death to another, and are spectacularly good at it, and are suited for virtually no other purpose.
A knife with poison on the tip, or barbs on the blade, intended to maim and kill and unsuited for other uses? Yes, that would be evil, as a gun is. Hunting rifles and target shooting guns? Yes those are tools for another purpose that can be misused for harm, as a cooking knife or a car can. But these aren't the things we're talking about are we? I'm not a fool, or incapable of judgement and nuance, so don't try to condense this view as if I am.
Guns are exceptional, in how well made they are for their purpose, how terrible that purpose is, and how frequently they are applied to it. The fact that other things have some or all of these qualities doesn't really change the calculus.
