We create our own hell it is the sum of all our decisions (and sometimes we are placed there). How do we escape even if we are not the cause?
The only thing anyone needs to do in order to escape hell is to love God, his creation, each other and have faith(be positive).
We are to understand that there is one God and that God created all things -- that is it. We play with fire when we claim to love God, but not all his creation. If you hate your neighbor, you hate God and you have arrived in hell.
