pope emeritus

Former Pope Benedict cited his advanced age and failing strength as the reason he stepped down from the Church's highest office on February 11, though recent comments reveal a different motivation behind his unusual resignation, the first in 600 years.
He has a debatable track record vis-à-vis the Argentine church's relationship with the junta in the 1970s Dirty War, which strained his relations with many liberal Jesuits worldwide. I don't like this story. What's really going on here?
