Being a Christian, I’m sorry, too-but that is as far as it goes-he lied to get here, endangered everyone both on the way, and while he was here and among the living, without a thought or a care. That family and girlfriend should not profit from his bad behavior any more than the family of an imprisoned or dead criminal.
I think it might be wise if they decamped with haste to another country-if a lawsuit does not encourage that, public shunning-like the Amish do-might do the trick.
Good suggestions.
