I do think Mark would kill Joker but these "just kill Joker" match-ups always ignore the fact that Joker isn't just going to stroll up and fight whoever he's going up against
Like in Injustice, Joker tricks Superman into killing his own wife when Joker and Superman fight
Superman then immediately executes Joker, but the damage is already done and Joker essentially wins because it sets Superman off to become a tyrant

Joker doesn't care if he dies, he just wants to drag everyone else down with him
Mark could kill Joker but Joker would do something to make Mark lose his morals in the process (not hard since in Mark's own comic a talking dinosaur managed the same)
