I can't say that being an irresponsible playboy is a worse life choice than being a lecherous greedhead old tyrant.
I think that Ramfis would be LOTS more fun to hang out with than, say, Bashir Al-Assad, who seems to have been really good at following in his father's footsteps.
Ramfis was responsible, so far as I know, only for the accidental death of some equally fatuous Spanish duchess.
I would say that the world in general and the Dominicans in particular are better off because Ramfis chose the life of a Ferrari-driving, womanizing, scandal mongering, playboy than another Baby Doc or Bashi Al-Assad.
I think we can acknowledge that the Generalissimo did build roads and unify a disorganized backward country, but he probably did all that a tyrant could do, and no second act was necessary or even desirable.
