You finally get it!
Just as the words of a dictator to slaughter innocents are culpable when they are acted on, so also the words of someone who has manipulated and controlled someone of diminished mental capacity are culpable when they are acted on!
You understand!
A dictator uses the military and police by force to kill people. The dictator is then an accomplice.
A gun is an inanimate object, it does not kill unless acted on, just like speech.
Therefore, ban the gun because it has the same characteristics as speech.
All human beings are responsible for their own behavior, even when the behavior is suicide. No matter how much a person gets encouraged to commit suicide, in the end the ultimate choice is up to the individual.
