To clarify, instead of intent a better word may be knowledge. If the supplier knows that the user is going to use the tool for harm but gives the tool to the user anyway, then the supplier shares culpability. If the supplier does not (reasonably) know, either through invincible ignorance (the supplier could not reasonably know) or the user’s deception (lying to the supplier), then the supplier is not culpable.
So the potential to do harm should never be considered?
