Obviously, a diagnosis of sociopathy is not socially acceptable. We gotta have a law to protect the rest of us somehow. Social Justice demands we do something to make everything "right" for everyone, and some personality disorders are just not compatible with governmental actions designing to make everyone do right.
If we begin killing all babies with some genetic condition pre-disposing towards sociopathic tendencies, we would likely be killing not just the Hitlers, the Lenins, Stalins, Pol Pots, Maos. . . and such. We would also be killing the Hillaries, the Bush clan, the Rockefellers, the Buffets, the Obamas, the Nixons, and the Colonel Sanders. In fact we would not be able to staff our alphabet government bureaucracies, or the think-tank intellectuals with vast ideas about governing the world.
And what would we do without the Siros and the babes?
nah, all we gotta do is really put some limits on the power government can have. That woulda fixed all those historical tragedies.
and, clearly, we gotta put some limits on the wine-brewers/party timers to stop them from killing the DutchJazzers. That's called laws which protect our rights to life, liberty, and such. That's why "no government" is not the answer, either.
