In my opinion:
Hell is the in my belief the lower vibration astral realms.
Heaven is the highest vibrational plain.
With that being explained I believe people go where they think they belong. Heaven is open to all, yes that includes the wretched, the wicked, and the devout.
The life review is exceptional important because that is where we see the pain and joy we caused others. It is where we learn and heal from this life.
Remember: This life is only temporary so make the most of it
