so yes, assassinations are well within Jokers MO
and with prior knowledge of the MCUs timeline they certainly would kill tony or nick or somebody, the movies also show that none of the Jokers are dummies by and means so its within their character to launch a preemptive strike; especially Heaths Joker who was known for planning intricately
Thanks for proving my statement correct, none of the Jokers ever tried to prevent someone from becoming a hero. they only ever attacked people that were already established and were a active threat to them.
