true, he wears a purple suit after all but, he's also managed to restrain himself (long enough) when necessary for a bigger plan.
Joker also knows Batman, his limits (self imposed and/or otherwise) and he plays on them. My recollection of The Joker is someone who has a little of the Satanic about him. He doesn't want to kill Batman so much as tear down Batman's morality, bring him down a few notches, make him do something that violently transgresses his personal code...
Given basic knowledge about Punisher, I feel he would be looking to push the "dead bodies everywhere" button in order to put Punisher's psychology under stress, rather than do what he does against Batman.
