My feeling is he let power get to his head and pervert whatever ideals he held.
Absolute power corrupts and corrupts absolutely.
No person can be trusted not to abuse power without checks and balances.
The Cuban Revolution is an instructive lesson on what to expect when people begin destroying their own country supposedly for its own good.
My sense always was that he had no ideals other then the desire to boss people around.
When you dig into any liberal no matter what they might say it always boils down to one thing, they want the power to make other people do what they say.
They all end up the same way, living like kings while they order the "little people" around. Every single time.
No exceptions.
