You are trying to using scare tactics!!!
In the late 1980s, TV commercials in the U.S. asked, "What goes through the mind of a driver who is not wearing a seat belt in a head-on collision?"
Then they showed crash dummies having there heads crushed by a steering wheel in a collision, and said, "The steering wheel!" Those were scare tactics, but no one complained because they were legitimate scare tactics. That’s what happens in a head-on collision if you are foolish enough to not put on a seat belt. To warn of hell is fearful, but it is absolutely legitimate, because the Bible says that it is a fearful thing for a sinner to fall into the hands of the living God.
