Keep in mind utopian failures are not a societal thing they are a species thing. In all cases human utopian societies are subverted and corrupted by a parasitical sub-species of humanity, psychopaths. Quite simply remove them and a lot of humanities problems will go away with them.
Be careful trimming our claws. You wouldn't want the 501st to have fought without a Lt. Speirs now would you?
"Winters assessed Speirs as being one of the finest combat officers in the battalion. He wrote in his memoirs that Speirs had worked hard to earn a reputation as a killer and had often killed for shock value. Winters stated that Speirs was alleged on one occasion to have killed six German prisoners of war with a Thompson submachinegun and that the battalion leadership must have been aware of the allegations, but chose to ignore the charges because of the pressing need to retain qualified combat leaders."
I don't think they need to be done away with, but maybe they need to be better used or positioned: keep the claws, but keep them away from the face.
