It is a great pity how the Catholic Church treats its best, isn't it? A man like Guevara, highly educated and purpose-driven, would have had every chance to make a stellar career outside the priesthood. If he had decided to go into private practice or government service (IIRC there was some period in his life where he considered emigrating to the USA), he could easily have earned a fortune, a professorship or a ministerial post and multiple awards. Instead, despite his many publications and great research work, he was left to languish in a bush hospital and only trotted out for conferences, and all because of his stance on divorce. He wasn't even a Liberation Theologist - by the standards of the Latin American church he was barely a liberal. But I guess being friends with John XXIII is a millstone around anyone's neck these days.
Damn, his Thalidomide study alone should have earned him the Nobel Price if there was any justice in the world.
