Got it, killing fellow muslims is a ticket to that whorehouse in the sky they call paradise.
So long as the fellow Moslem has been identified as an apostate by someone in the killer’s imamic chain of command.
I am not sure it is exactly a whorehouse. The description of the girls one is exposed to in that place with cool shade where rivers flow makes them out to be something like non carnal androids with no bodily functions.
