Whilst I have met one lady in spirit who was unsettled (it was a lady who had sadly had life taken by another person) I have never met a single spirit who was trapped or earth bound and unable to move on peacefully/ cross over
I don't believe in hell either. None of us will ever know the full detail of what's beyond but as a medium in all the time I've practised, I've never known anybody to be desperate for me to help them because they were trapped. Only 1-2 who had been murdered, and their reasons for sticking around were because they wanted to communicate to the people investigating and their families, what had happened to them. They wanted justice and they wanted to stick around until the people who did it were caught. Once they were, they were fully at peace and they crossed over peacefully to be with family etc.
So next time you worry about anybody being trapped, please don't even if they stuck around , it's not forever. It's for a very short time and they receive lots of help once they have passed, they are not alone , I believe they are with loved ones and they are waiting to greet them
