The evidence seems to suggest that the people the state wants out of general circulation fare no better when they're tossed in prison or otherwise hounded/destroyed.

You also require doctors acting as criminals, with weak oversight to make your fears come true, in addition to a criminal government. If a government goes really wrong, and wants you out of the way, they'll get their way. Jean Seberg for example, didn't need to be locked up to be destroyed. We didn't need to lock people in hospitals to ruin their lives, we just used a blacklist.

You shouldn't be so frightened by your personal history that you lose sight of the fact that the root cause is a government out of control, not the means they use.
