[DC] What would Joker think of Joe Chill, if he found out that Chill was the one who caused Batman to exist?

Joe Chill cannot reveal that Batman is Bruce Wayne because the other criminals would kill him for creating Batman, but what about Joker, who loves Batman as an archnemesis?

Joker isn't going to "respect" him or anything. Joe Chill is just a common street thug so Joker can't get anything of value out of his skills.

If Joker can use Joe Chill in some sort of way to torture Batman, he will. Otherwise, he's just giving him a sarcastic thanks and shooting him in the head. 

In the Three Jokers, the Jokers kidnap Joe Chill and plan to dump him in Joker Venom to transform him into an Ultimate Joker but Chill is saved by Batman.
