I don't think it is objectively wrong to teach your kids about Hell, if that is truly what you believe. But I do think it has to be done very carefully, using prudence as responsible, good parents. Too much focus on Hell is definitely not healthy for anyone, especially kids.
"Of course, everyone will claim they respect someone who tries to speak the truth, but in reality, this is a rare quality. Most respect those who speak truths they agree with, and their respect for the speaking only extends as far as their realm of personal agreement. It is less common, almost to the point of becoming a saintly virtue, that someone truly respects and loves the truth seeker, even when their conclusions differ wildly."
