How to become a monster like ISIS in 5 easy steps

Are you able to behead a person? I mean cut his head of with a knife, sharp or not? Are you able to rape a woman and maybe bury her, but she is not dead yet. Or maybe you are in the mood to cut a child in half? Or maybe you like cutting someones fingers off? What do you say, castrate the man? Or cut out his heart and hold it in your hand for all to see? Do all of those things and you feel great doing it?
