You'd have thought that meeting a talking stag that warned him of his destiny would have struck him as unusual and put him off hunting. Oh no – of course not. While his wife – a rich older woman (what a canny man) – was busy being hospitable to his parents, he was out chasing deer. So he'd only got himself to blame. That he thought he was killing his wife is not the strongest defence I have ever heard – and what was he doing out after dark anyway?
Then the smooth talker who has already justified his patricide and matricide as being his unavoidable destiny as predicted by an animal not renowned for its conversation, claims that he has been hospitable to a leprous angel. 
This doesn't begin to compete with stories of maidens protecting their virginity and walking about carrying various lopped-off bits of their bodies after punishment by rapacious but powerful men. The Catholic church is really not trying with this one.
