Should they? Of course not. But they will if they are brainwashed or coerced enough. Remember, they teach jehoopla is the Master of Surveillance, reading your heart and watching your every move, punishing you with carnivorous birds and death if you are not a Righteous Tattletale. You not only share in the sin of the sinner, you commit your own sin by covering things up.
In my experience, most teens understand the coercion and brainwashing and don't hold a grudge.
