I am 110% correct that no matter the universe/storyline, doing this to this kind of Joker and then not following through would WITHOUT A DOUBT lead to the Joker killing him and his son when he inevitably breaks out of Arkham. That being said, a competently written Bruce would realize this and a very generous "Witness protection" plan would appear and this guy would live some upper middle class life on the other coast. Joker would sniff around for the guy but cut his losses when he sees the guy up and vanished.

What's funny is, in the moment, if you're this guy you 100% dome Joker right there. It's objectively the correct decision because you KNOW he's gonna get back at you. Batman is powerless to talk no jutsu into keeping his codependent rival alive in any storyline of this happening.
