It's pretty much the same thing as public executions, to instill fear into people so they don't do socially incorrect things that doesn't benefit their society or culture.

first you need to know that in hell and heaven the time is not the same as we perceive it in life.

eternal hell is not rehabilitation as there wont be a life to return to after you have burnt in hell. it's a place where you pay for the sins you committed in life that you where warned not to do yet arrogantly can't admit that there is a creator. God forgives all since but the one that does not admit his existence. there are some people who burn for a period and then there are those who burn forever as their sins are to great.

God does not enjoy watching humans suffer as he already knows what awaits those who do suffer. we as humans do not see what he sees. everything that happens in life happens for a reason. a person who suffers on earth might enter heaven without any punishment whatsoever as he/she has already suffered in life. then there are those who suffer in life and in hell as well as those who have it good in life and In heaven.

sometimes God puts others in situations that will make others wake up and then there are those who think like you that say because there is suffering on earth then there can't be a God. the problem is that people think that if there was a God then there should be heaven on earth which is ridicules as that would make the test of like non necessary and we would all be in heaven in the first place. God already knows everything but the test of life is here so that we get to find out what's going to happen and why we end up in hell or heaven depending on the choices we make otherwise people wold be asking themselves why they ended up in hell or heaven.

You're taking a very modern, liberalistic view on the idea of "punishment". For a lot of people - hell, for the vast majority of people - punishments are about delivering justice. As such, eternal hell is there to torture those who deserve to be tortured.

I don't personally agree, but I don't see how you didn't see this.

the purpose is to terrify because scared people are easier to control.

Well, he cannot actually prove it, but the fact that there is a complete lack of evidence supporting his existence while the traits that he supposedly has have been proven illogical (and quite francly are absurd), there really is no reason for a reasonable person to believe in him. And the fact that there are songs and stories written about him doesn't change anything: Believing that Santa is real is borderline insane.

But no, neither he nor anyone else can truly know.

(Yes, I'm obviously joking. And I know that believing in God is a different thing and has nothing to do with insanity. A lot of other factors are involved in such beliefs.)

I wouldn't want to go to hell permanently of course! But what the hell, pun intended, do we know. I belive God knows better why this is neccesary :(

Humans don't have the intelligence needed to understand such a thing.

The better version of that argument is, people born in the wrong parts of the world are doomed to hell because they were born in the wrong culture, why would god make it so that perfectly good people are sent to hell because they lost the birth lottery?

well God does not punish those who don't know.

God sent a messenger to every tribe on the planet so people would find out about the one God one way or another

I'm not buying that. The native american peoples were isolated from the rest of the world until the 16:th (?) century.

Even if a messenger magically appeard there, a person's religion is almost always determined by the culture in which they live and although missionaries have suceeded before (Germanic and Slavic peoples, Indonesia) they have also failed (India, China, Japan). Are you saying the Japanese engineers who volonteered to clean up Fukushima instead of the young are still going to hell because they're non-religious?

If god will put me in hell for eternity just for not believing in something I've never seen nor felt then so be it, I'll never worship a god like that.
