Karupan - If you deliberately keep spreading a lie to profit from it, you should be held responsible IMO.
By that definition, this should apply to Santa Claus story tellers and the Church? Can I sue them for poisoning the life of my kids? They are teaching kids that lying is ok, after all.
Some punishment might be ok but the prison system in many states is more like torture. One example is that some of them design the cells to have maximum echo... When you speak it drives you crazy.
