Joker made Batman's life "hell" (you know, so much hell that he had to only live in one giant mansion mostly) because Batman a) won't just kill Joker and b) will let the Joker go to save a civilian that the Joker has endangered. Fisk is under no such limitations. Joker comes to play with the big man, he's going to get destroyed. Plus Fisk, unlike Batman, will mobilize an army against the Joker if Joker interferes in anything Wilson is planning.
