You have based your actions on an assumption that I consider dubious. People who want to kill will find a way. We’re fragile creatures, easily dispatched by a single hand-strike to the adam’s apple or temple, by a single stab of a kitchen knife, by a few bonks on the head with a hammer or baseball bat. A gun can make killing easier, but is not necessary.
Destroy every gun, and the killing won’t stop.
The real problem here is why do people want to kill other people. Wish I knew.
