We could just nuke ourselves, put ourselves out of this misery, and let the rest of them suffer through life.
Rape is a horrible thing. Child rape is a horrible thing. No reasoning can explain such behaviour, but the point behind such stories, does relate to border controls, if this man wasn't there, this rape wouldn't have occurred.
He will be imprisoned and eventually released, assuming he isn't found to be psychotic, in which case they might keep him locked up.
I would hope such a man would be returned to Iraq after his sentence, and refused any further entry to the EU. Worried that such events might not transpire, and he might get to remain here.
The child will be broken and distraught, no doubt will be in need of counselling, at least a lifeguard was there to find him help, and he did tell someone, and it wasn't hidden by the child.
