Guns Are Designed to Kill Bad People?

In a video @ https://www.facebook.com/watch/?v=149148723912527 someone suggests that Ben Shapiro is hypocritical in opposing abortion but not supporting gun control. Shapiro replies that abortion kills babies, but "Guns are designed to kill bad guys if operated by a proper person."

That argument is all over the map. Guns are designed to kill, period, and that's a mighty big "If." Moreover, what is a "proper person"?

Can anyone point out some specific fallacies in this argument?

Shapiro is highly religious and holds the world view of "good guys" and "bad guys." Immediately, I can think of the false dilemma or the cognitive bias black and white thinking—a way our brains deal with the discomfort of complexity by oversimplifying the world in a child-like manner.

The "designers" of guns design and create guns to make money, so unless Shapiro can provide evidence as to why guns are "designed," he is either factually wrong or at best, making an unfalsifiable claim. Gun designers in Afghanistan create guns perhaps to kill Americans... the "bad guys," so even if he is right, he is wrong.

cherry picking Guns are also used by "improper" people to kill good people.

It's also red herring because the initial discussion was about gun usage and gun control, not gun design.
Also non sequitur if the implied argument is that since guns are designed with the intent to kill bad guys, there should be no gun control.
