Scientifically, you would want to kill the Id. According to this Freudian model of the psyche, the id is the set of uncoordinated instinctual trends; the super-ego plays the critical and moralizing role; and the ego is the organized, realistic part that mediates between the desires of the id and the super-ego. The Ego does not destroy it mediates. Our culture today just has people with weak egos so they can control the Id or Super-ego. without the ego the instinctual Id will consume the super-ego.
