Doomslayer in JSAB ( after "New Game" Jsab) (after Doom Eternal)

A/N This is my first story so plz go easy or me ( or don't) , also this a a fan made story so ,I may change something (I do not think it is a may).

The DOOMSLAYER has just finished killing all demons on earth and finally had a chance to visit earth and help the humans( maybe) before going back to hell(doom) to kill demons. However the portal that suppose to send him to earth send him to an unknown location and him encountered an unknown entity. After the encounter with the entity he was transported to a strange place that has tress or a least it is suppose to be . It was there he was told that he needed to get to the tree of life in order to get back to his Dimension. He will come back home but will he leave the dimension as a hero or will he leave being remembered as demon?
