Always best to obey religious commandments?

[xxVampireMagickxx]

Do you think there can be situations where it is actually in someone’s spiritual and/or physical best interest to disobey their own religious laws? For example, if a Christian woman is a recovering alcoholic, and is married to an alcoholic man who is constantly drinking around her and keeping alcohol in the house, and refuses to change even though it’s for both of their good, is it in her best interest to keep enduring these tests and run the risk of falling back into her old habit, or is it better to divorce him and get on with what would probably be a better, cleaner life? Or if a young Muslim girl had been raised in the west by a pseudo-Muslim father who believed it was okay to have 300 wives and treat them all like garbage, that girls were worthless until they had children and that it was Allah’s will that he beat anyone who wasn’t Muslim to death, this girl is pretty likely to grow up resenting Islam unless someone shows her the flaw in her father’s way of thinking, and if she were to loose all respect for her parent’s beliefs, she would not longer be honoring them as Allah wanted. I could give other examples, but for now we’ll stop at those. What do you think? Can it be in the greater interest of someone to break a spiritual commandment, or would it simply be taking the easy way out for the woman to divorce her husband and for the girl to stop respecting what her father thinks?
