To disembowel a person or an animal is to cut them open and take out the bowels — the long tubes in the belly. It is a violent, very physical verb. In history it names a kind of killing or punishment; in hunting, older writing uses it for taking the guts out of an animal, though cooks today more often say gut or clean. You will meet it in history books, crime stories, and horror, not in polite small talk. Though actually, a few writers stretch it for a review or an attack that rips the insides out of an argument, but that use is colourful and not the first meaning. The word is never gentle. If you only need “hurt badly,” this is far too much.
