The answer is that it is impossible to control this stuff. The Technology is spread too far and wide, and now millions of people can create robotic devices that can carry an explosive charge to attack an adversary.
There is no control over it. The only control that can be brought to bear is the teaching of self control, preferably started as a child in a normal male/female family environment.
What people believe matters. What they are taught, (and also what they are not taught) matters.
You cannot control people, you can only encourage everyone to control themselves. This is how Christianity created Western civilization.
It was an ingenious system that convinced each individual to control themselves.
If Christ was invented by man then Christ is no better than the basest con game.
However, Christ wasn’t.
