That should read cannibalism Maarra with 2 rs.
While it seems the adults were broiled the Crusaders put the babies and chil;dren on spits and bartbequed them.

You could read 'Consuming Passions" a book I think dedicated to Cannibalism in early modern Europe and "Cannibalism; a modern tabboo".

I would also remind you that the Catholic mass itself is a cannibal ritual where the people of the church are emplored to eat the body and blood of Jesus Christ.
