There is an old saying - the road to hell is paved with good intentions. The way I understand the saying is that even well meaning people can do harm.I think better would be to grow out of fear. Fear itself is not bad, because it helps person to understand and can prevent person to hastily to make bad a choice. But, it is not good if it rules. And there is no reason to allow fear to rule.
For example, in the case of fear of hell. I think it would be good to understand that hell itself does nothing.
And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
Matt. 10:28
In Biblical point of view, it would be reasonable to fear God rather than hell. But, God is good, He doesn’t do anything evil, so I don’t think there is good reason to fear Him, unless maybe if you are evil and do bad things. Even then, if you regret that you have done wrongly, there is forgiveness available. Only case when the hell comes possible for a person is that he is truly unrighteous and wants evil. But, would evil person fear hell? Would it be bad in that case?
There is no fear in love; but perfect love casts out fear, because fear has punishment. He who fears is not made perfect in love.
1 John 4:18
I'd be prepared to go to great lengths to save my daughter from a burning building even though she would most probably asphyxiate before the flame reached her. Can you imagine how far a person would go to safe their child from burning for 50 or 100 or a thousand or a million years?
I suspect that is why we see well intentioned groups such as the Taliban who have carried out extremes of puritanical culture.
They presumably don't want their child to burn for an extended period of time so they cover women in Burqas and block out the windows and forbid women from being public figures - that is what I suspect, that it is all to save their children and themselves from the fear of burning.
In my opinion.
