Correct. Man invented hell. It as make believe as other after life torment club religions use to manipulate and control people.
No. Hell is not inescapable able. Nobody needs to escape something that does not exist.
While the LDS doctrine of hell is a bit more "compassionate-" One only suffers pretty miserable for maybe 1000 years or so, then gets some kingdom of glory, it still pretty horrible. And for the rest of Christianity, well hell fire and brimstone forever seems extreme don't ya think?
And personally, I find a God being that threatened some sort of horrific punishment, short term or long term while at the same time requiring us to forget all we supposedly learned and agreed to before hand (I don't recall that do you really?) absolutely abhorrent and repulsive. Such a being should be rejected for the monster it seems to be. It is like going the 150 hours of college to qualify to sit for the CPA exam. Then after 5 years of education when I go to take the test, the proctor waves a magic wand and says "forget all you learned and go take the test. And if you don't get it right, sucks to be you, but you will suffer for it. Sorry. Even though you don't remember you agreed to it. And yea you agreed without sufficient knowledge to know what agreeing to it meant. But hey, have a happy life!"
What utter nonsense really. Yet this is in essence what you think it God's truth.
The idea that there has to be opposition in al things is also nonsense. But that is a topic for another day.
