And 7:43 doesn't say we cannot do Malice,if you consider it malice
"And We will have removed whatever is within their breasts of resentment, [while] flowing beneath them are rivers. And they will say, "Praise to Allah, who has guided us to this; and we would never have been guided if Allah had not guided us. Certainly the messengers of our Lord had come with the truth." And they will be called, "This is Paradise, which you have been made to inherit for what you used to do.""(7:43)
Does any part of the verse say we cannot laugh at anyone being tortured for their sins?
