History shows religion is the world's worst source of "ethics".
Christianity - supported slavery, rejects women's sufferage, encourages repression of homosexuals, oyster eaters, and so on.
Judaism - still the Old Testament. Better, more reasoned than Christianity, however, which likes it's Old Testament straight and hasn't found need for the New.
Islam - cruelties beyond belief. As are the other Eastern religions.
Nope. Lousy place to try to find ethical standards.
