Is the giant from Jack and the Beanstalk a cannibal, or is he of an entirely different species than humans?

(Also, I never understood why we’re supposed to sympathize with Jack–he’s a total ass. I get it, he’s poor–but after you had the golden eggs, why would you come back for the harp?! He didn’t need the harp, he had golden eggs! And what’s up with the giant’s wife? Is it just me or was there always something sketchy about her?)

If not a different species, what do Muslim giants eat, as cannibalism is haraam?
