How far should law reflect morality?

The truth of this matter is based on the fact that morality is only applicable to the person in one society and in a determined time, given that moral will change depending on the population you are talking about and the period in time you are referring to. Having said that, law should reflect morality as long as this morality is secularized and is not contrary to hard facts or logical reason, therefore the only moment in which a law should not reflect moral is when both moral and the benefit of the people are clashing.
