Why is it so hard to stay a good guy?
Or, why is it so hard to give up power.
Look at the Castro Brothers, they were once heroes of the revolution (I mean that sincerely) and now they are just the worst.
Look at Robert Mugabe, hero of Zimbabwe's independence, now reduced to destroying his own country to stay in power well into his 80s.
Look at Chavez. It's hard to remember now that he too was a hero.
In Africa, Museveni of Uganda helped depose Amin but has stayed in power now for 24 years and counting.
Sadly, Paul Kagame appears to be the latest case. He was a post-genocide hero, but most recently won re-election with 93% of the vote after vigorously suppressing opposition parties. Now the NY Times reports that Rwanda's leading opposition figure was just arrested today. Of course Paul has a long way to go to reach Mugabe longevity; he's only got 10+ years on the job at this point.
Are these all manifestations of the same personality type? Does fighting for a cause somehow delude you into thinking you are indispensable?
I find these cases simultaneously baffling and heartbreaking.
