The problem of hell is a difficult one, but put in simple terms, it's about people who make bad choices. A lot of people believe in a place called hell where people who do bad things go when they die. The problem is that if people go to hell, then it seems unfair because it means some people are punished for making wrong choices, even if they had no other choice. It's like punishing a child for something they had no control over. So, the problem of hell is about whether it's fair to punish people for what they didn't have a choice in. Many people believe that the punishment should fit the crime, so if someone doesn't know the difference between right and wrong, then it's not fair to punish them.
