Guns are not necessarily bad because guns are not the only lethal tool in this world, many murderers can kill with a pen or a book. To me, good or bad is due to human behavior, we can't blame technology or anything. All of them are used and controlled by humans, so it is impossible to say whether it is good or bad. Our world wouldn't be a better place without technology, it would only be really nice without the villains. But that will never happen, as a society, there are always bad and good people.
I am not really in favor of this that much. I feel like if guns never existed, then the amount of murders would drop a lot, and that is good enough for me. Doesn't mean there wouldn't be any murders at all, there would still be murders, pen or book sounds a bit silly to be fair, I would guess a knife would be the alternative of the gun not a pen lol, but yeah there would still be murder yet there would be a lot less.
I do not mean guns as just on police or anything, I mean zero guns anywhere in the world, no guns at all, no soldiers, no police officers, none of that should have a gun, totally gone, then we will have much less murders without a doubt. Just because there would be some, doesn't mean there would be as many.
