Religion: When conservatism kills

What kind of religion teaches married women in Africa that they must not use condoms, or refuse to have sex with their husband, even if they know he has been infected with HIV/AIDS? What kind of religion teaches that the wife must be faithful (not generally a problem) when the husband is known to be blatantly otherwise (and this is condoned)?

What kind of religion forces people to choose between faith and "salvation" -- and emotional and spiritual joy, not to mention the fullness of life itself?
