If there were no guns, there wont be any police to protect you from the neighborhood bully, or rapist, because police wont have guns. So now that 300lb guy who wants to enslave you can use his physical size to do it.
You wont be solving anything other than helping the dumbest biggest people take over the world. We will be back to cave man status where men rape women simply because they are bigger and have bigger fists.
Without guns and bombs people would be even more afraid. A rapist doesn't need a gun to rape a woman with his bare hands. A violent person doesn't need a gun to break your neck. What are non-violent people supposed to do? You'll be even more afraid than you are now because anyone will be able to take anything from you just by beating you up.
