Is a person considered an infidel if they laugh when seeing terrifying images of angels of death in cartoons?

It is not permissible to embody angels in films or to consider them deities, nor is it permissible to watch animated films that contain শরীয়াহ violations or concepts that contradict Islam. As for laughing when watching such things, if the questioner suffers from the waswas (whispers) of disbelief and mockery, she should ignore these waswas and avoid watching such films.
