Why were guns invented and did the person not mind all the deaths that would come with the invention ?

@Jackaloftheazuresand: Cars were designed to make people's life easier.Instead of taking hours or days to get somewhere cars and vans a what you call progress.The deaths were they are involved are usually because of human error and are accidents.

@Pureblossom: And guns used against other people aren't? A normal person doesn't just shoot people.
