My grand da suffered serious injuries wen he was kid during Holocaust and he and his uncle were forced to leave Germany to save life . He always told me humor was one of the factors that helped him to stay alive. I like dark humor but same as acid humor or spicy humor you have bad taste dark humor and good taste dark humor. So a bad taste joke will be a bad taste joke it doesn´t matter if spicy , dark, green, acid... key in humor is balance between intelligence , transgression, respect, irony , etc. BALANCE. ;)
