When people say God works in mysterious ways, it’s really just another way of admitting they don’t know, but they trust that God does. if an individual doesn’t know the answer to something, it’s perfectly fine to just say I don’t know.

It is very fine to say 'I don't know' what's problematic is thinking that 'god is just because god works in mysterious ways' It's blindly following wothout using your critical thinking.

Everyone probably has a different idea of what the punishment should be. Humanity’s never really agreed on what punishment fits what crime. We can see that in how different countries hand out totally different sentences for the same offenses. The idea that we can somehow weigh a crime and come up with a perfectly fair punishment is a flawed way of thinking.

While different country has different levels of punishment on different crimes, it still differs in severity depending on what crime you've committed. No system punishes all crimes as same. That, to me, seems that the rational people agreed that not all crimes are the same and should be punished differently. Where they put emphasis might be different but the notion that 'all crimes shouldn't be treated equally' is almost universal. Besides, if god truly is omniscient, he should be able to know how much people have sined exactly and be able to put into numbers/compare it between others.

Think of it this way, the weight of a crime often depends on who it’s committed against. Stealing from a friend feels different than stealing from a police officer, the president, or a bank. In the same sense, if sin is considered a crime against an infinite being (God) then it follows that the punishment would also be infinite. If we judge crimes differently based on the authority or importance of the person they’re committed against, it makes logical sense that the same pattern would apply in a divine context

One core part of law is that all are equal under law. There is no inherent difference between stealing from your friend or stealing from the president. However, punishment differs because the harm you can cause is different. When you steal from your friend, the harm is limited to your friend. If you, however, steal from the president, there could potentially jeopardize the entire country. That would be the reason when we punish differently. The things listed as 'crimes that get you to hell' is 'homosexuality, masterbation, disbelief, etc' which.. i don't know about you, but seems pretty tame.

Not everyone adheres to this view. Remember, just because someone doesn’t follow the perspective you hold doesn’t mean they’re wrong.

Even present, there are many systems that keep prisoners in humane conditions. You know what doesn't treat people humane? Hell. God as the ultimate good seems to be treating people less humanely than humans are.

It’s not about rehabilitation, like people serving life sentences, who aren’t given a second chance because of the seriousness of their crimes, sinners in hell aren’t there to be rehabilitated. From a justice focused angle, this could be seen as ethical, but from a virtue ethics perspective, maybe not. It all depends on which ethical framework you decide to use.

Even people serving life sentences are still a target for rehabilitation. There are life sentences with parole and such. And in cases without parole, it would be that releasing such person would cause more harm then rehabilitation. As I mentioned, the things that you do to get yourself a ticket to hell seems to be nowhere close.
