For better or for worse, the body's many constituent parts work together to maintain their own mutual integrity, each playing an essential part but at the same time being completely dependent on each other. And then a given body as a unity with a certain ascendant character, could very well be destructive to its own self and its continuity, which itself is a relation in terms of other bodies within a greater organizing body like a society. Hence the fool and villain/criminal archetypes.
