guess ramayanam is a sentimental drama and if one looks at it from a lyrical / literary perspective as one would look at Shakespeare's or even Tennesse Williams works, then it shdnt matter much
as for morals, they are but a reflection of the times - it was considered ok and even a moral neccessity for a woman to jump into her husband's funeral pyre (probably its still being practised in some rural parts of northern india) 50 years ago, honor killing of newly wed couples with the boy /girl from different caste backgrounds still being practised and accepted in many places in india, etc etc, just the same way sharia is practised in islamic countries around the world
wonder if someone would take a different / radical look at the conventionally accepted story of rama - sita and give a twist showing rama's advances towards other women in the absence of sita !! ? perhaps we need a desi Dan Brown to come up with something like that to challenge the 'holy cows' of indian mythology!
for the 'so-called' morals espoused and practised during biblical times, watch / read Richard Dawkins' 'The God Delusion'! it was morally acceptable to kill ones own son to appease 'god'(yaweh the jewish one) and also stone ppl to death etc etc - and later on, it was acceptable to burn women at the stake for charges of heresy and practising witchcraft etc - but those times were different and real
likewise ramayana if not taken as a sentimental story, but a series of events that allegedly happened, ought to looked at time-context wise
