(CNN) — Pope Francis is being painted as a humble and simple man, but his past is tinged with controversy surrounding topics as sensitive as gay marriage and political atrocities.

Questions linger about Francis’ actions during the nation’s dark days: the so-called Dirty War, when Argentina was ruled by dictators. The gay marriage issue came to the forefront during Francis’ political fight with Argentina’s president.

The conservative pontiff may hold firm on some issues, experts say, but he may be flexible on others.

“If you think that (Francis) isn’t going to change anything, you’re wrong,” said Gustavo Girard, a retired doctor who knew Francis during his early years in the priesthood. “But is he going to approve of gay marriage tomorrow? No.”
