Huh?
When did Dante ever claim people are not to blame? Dante is not blaming guns? But anyone who thinks regulating guns does not help keep guns out of the hands of some nuts and criminals is just not living in the real world. I know lots of criminals who wouldn't touch a gun while committing their crimes
Guns are a tool. Banning or over-regulating some but not all wont prevent gun-related crimes. Bad guys'll just get whatever's still available.
In their purest form, a gun is simply a metal tube, a firing chamber, and a bullet being forced out of the tube by a small explosion of propellent. It's a many centuries old incredibly simple device unchanged since it's invention. Banning some because one is ignorant about firearms and thinks an assault rifle is a weapon of crime isn't protecting anyone. Many mass shooters used perfectly legal guns never on anyone's ban wishlist. Revolvers, hunting rifles, shotguns, etc. Going after the scarier looking ones reveals an ignorance and immaturity about the subject while doing nothing to deter crime.
Wanna regulate something, keep bad guys in prison their full sentences. If you're running out of room kick out the mandatory setence minimum types out early instead of the violent criminals. Or better yet, nip it in the bud and just execute all violent criminals. Works in China and the Middle East real well.
