He was a repressive tyrant and terrible gerontocrat who fought against the previous repressive tyrant and the malign influence of US capitalism. That he’s dead just means one less dictator in the world, and unfortunately there’s a long line of them waiting to take over everywhere.
I might care more if his absence made a difference for the people of Cuba, but his brother is already holding the reins of power.
I share Jeff Shallit’s opinion. He murdered thousands of dissidents. He gathered up gay people and put them in labor camps. He was dictator for life, and passed power to his brother, who is the new dictator. You can point to a few good things he did for Cubans, I’m not denying that, but in general, he was a tyrannical monster who seized power for himself and never let it go.
