Feels so guilty for past actions that they turn to religion

That would be the character of Berthe Erica Crow (called "Crow"). Fifty-seven-year-old Crow wears black and is deathly pale; she looks severe, rigid, as if life has used her harshly. Hospital records show she had problems related to chronic alcoholism and was frequently picked up for vagrancy. She gave up drinking when she became religious and started the Good Salvation Soup Kitchen on Skid Row. She works as a cleaning woman in Sunset Towers. She seems shy, or perhaps guilty, to outsiders.
