The possibility that he had something to do with the death of Esther Ballestrino and the kidnapping of children is interesting.
In 1986 Bono was so compelled by the horror stories of Chilean mural artist René Castro that he went on a trip to the region to see the aftermath firsthand. That experience and what he learned about Mothers of the Plaza de Mayo lead to him writing "Mothers of the Disappeared" for the Joshua Tree album.
Seems weird in the context of him shilling for the pope these days, don't it? Going from, what I believe to have been, an honest person with a humanitarian heart to an absolute garbage globalist shill in a decade or two must be a pretty rough ride.
