Sounds like you dont want guns cause you're afraid you'll use em on yourself!
If i truly lived in dangerous neighbourhood like Mexico or parts of the USA with lots of criminals around and crime happening, then yes, I'd certainly be inclined to get a gun.
I would also be interested if I had a family and house to protect, as there have been home invasions where the residents were killed. But I don't live in such a setting at the present time.
Presently tho, I see no need to have a gun since my neighbor is a policieman who is professionaly trained in the use of firearms.
The incidence of violent crime is extremely rare where I live.
