A corpse, is the dead body of a human, animal or mechanoid. At first, it will be in fresh state but will deteriorate through time. It can be consumed before it starts rotting, humans may have negative thoughts but not animals, which becomes a free source of meat in scarce environments.
Corpses can be butchered, buried or burnt depending on need. Those that deteriorate completely will leave distinctive skeletons were they laid.
Corpses can also be butchered before they start rotting, to obtain human meat and leather. The cook will suffer the "Butchered humanlike -6" debuff and every one else in the colony, the "We butchered humanlike -6" debuff. Also affecting relations between the cook and the others, except colonist with Bloodlust, Cannibal or Psychopath trait.
