Does Morality Evolve With Time?
I think I agree with you that morality is subjective. In Europe walking in bikini at beach has no impact on morality, or having a boyfriend is not immoral. If you look at history, this perspective has changed over time. Since humans perspective of morality or even laws keep changing back and forth in time, that is why Allah sent Quran, which is Furqan. Quran gives us a standard to judge what is moral or immoral.
