There's very few products which everyone can objectively say are designed for killing.

Agreed, it's very rare, guns are absolutely one of those things though. They're the perfect evolution of the personal handheld killing tool. You just point it at the thing you want dead, push the button, and you've got a good chance of deadding it immediately with your first try.

Guns don't have a secondary use, like how a knife can whittle a tree branch into a nice spoon, or cut some thread, or skin an animal. Guns cause massive damage to whatever they are pointed at, and sometimes to the things around that thing too, if you're particularly unlucky.

They're the solution to a problem when you need the solution to be "escalate this situation to 1000% and start killing stuff".

Gun manufacturers who say they're made for defence and not killing must be delusional or confused about what their products do, or just lying to their potential customers for.... who even knows what reason.

They are made to defend yourself by killing the person you need to be defended from. Pure and simple. They are truly as cut and dry a tool for killing things as there is.

Nobody is out there shooting people defensively with some non-lethal mode built in to their high speed projectile metal lumps that tear through the human body, causing parts of it to explode and massive trauma to the surrounding tissues and organs.

Do guns exist that fire beanbags, or tranquilliser darts, or such? Absolutely, but none of us here are talking about those types of more specialist guns. We're talking about your standard gun, the kind they sell to lots of civilians in countries like the USA.
