But it’s odd that they regard sodomy of a boy child a crime if the religion views them as ‘pearls of eternal freshness’. Also, it’s not problematic for a man to sodomize a boy so long as that boy hasn’t hit puberty/doesn’t have facial hair. Something is odd with this case. I suspect it has to do with the boy’s father having been killed.
Child molesting in Arab cultures is a status related thing. Boys of lower status families are fair game for any male, and boys in their own families are fair game for older males in their families. Girls are married off early, but not usually molested because they would lose their financial value to their families if this happened. Boys, on the other hand, grow up to go on and molest other boys in their turn.
So possibly this man attacked the child of a higher status family or even somebody in his own family who outranked him.
