My feelings are ambivalent on this. Mugabe did a lot of excellent work in terms of expelling the colonialists who certainly didn't have Zimbabwe's best interest at hand.
Unfortunately, his behavior is like that of a monarch and that has certainly slowed the growth of Zimbabwe. Of course, salty westerners who are still angry they were chased out of Zimbabwe haven't helped with the many sanctions levied against the developing country.
My concerns are for the indegenous population who are yet to taste freedom ever since westerners stepped foot on that land. I'd like to say things would be better if Mugabe's deputy takes over, but given the fact this guy was personally groomed by Mugabe for years, the guava cannot fall too far from the tree.
The poor people of Zimbabwe will likely end up with another dictator or a puppet for western powers.
