like all questions in Judaism, there's no one definitive answer. I think 75%+ would probably deny mr. cannibal corpse a burial in a Jewish cemetary tho.
ps, I know this stuff cuz I was a Jewish Studies minor back in college.
Judaism also doesn't have a central authority figure like the Catholic Church, so it's more undefined exactly what's right and wrong...you kind of have to look at 1000 peoples' opinions and get a more or less consensus to even be mostly right.
