My thought is the following:
Could be Humans are creating their own "Haven" or "Hell" based on their deeds.
Every soul shall be attracted to the realms which matches with his/her personality...
Just like listening to radio station, but there is NOT ONLY 2 radio stations, there are many, hundreds, thousands, millions or perhaps unlimited.
And those who like Jazz shall tune out to the jazz radio station. those who like stand up comedy will tune to the comedy station and so on...
A realm where there's no chance of dominating and enslaving others, no possibility of invading or making a war with others might not be too interesting for a warlord.
He / she will be tuned in to the realm where there's ample opportunity to enslave people, warring with someone and do the things he / she loved the most and experiencing the things that he / she loved the most. (#hate, #fear, #pride)
A realm where there are enslavement of 72 virgins might not be considered as "Heaven" for a human rights activist. He / she will consider it as "Hell", he / she will either leave the realm or try to change the realm by trying to free all enslaved virgins. If it's actually the experience of 'freeing enslaved person' is an experience which actually he / she desire the most.
In the end, everybody will get what they wish for...
