Chandra sinned by seducing his guru's wife; he partially expiated by worshipping here. Sage Bhrigu, King Mahabali and the moon-god Chandra expiated their sins, worshipping Vishnu here. They can also be expiated by avoiding the major sins. Pope Alexander forbade Henry to hear mass until he had expiated his sin. The minor prodigies were duly expiated with "lesser victims". These were expiated by the sacrifice of "greater victims". God alone knows what remains to be expiated. I think this man has more than expiated his crime.
