So my dear Sridharan ji, we cannot take rama as an ideal husband and father. Thats enough. Even I too already accepted that Rama is an ideal king. Certainly no second opinion in that.
"It appears all other aspects whether Rama is an ideal husband, Sita an ideal sister-in-law, Dasaratha an ideal father, Kaikeyi an ideal mother etc are irrelevant because Ramayan is told in the true spirit of describing a Hindu family akin to the realities of family feuds that are inherent in a typical Indian society".
You meant that this stroy came to show the Hindu family feuds. But with a hero who is not fit for a family-head, but is totally fit for head of society... Yes. In true life also am seeing many such persons, who will run for others, who take much care for other feelings, but never even turn even their wife or son fell down. Many Ramas are around me. For Dasaratha, kowsalya, lakshmana, bharatha, hanuman, why not each and every character except my innocent sita, this rama was favorable... Even this sita too believed him forever and kept her mouth shut even when he drove her away when she is on her family-way. Finally, the real heroine (certainly there is no hero at all in ramayana) got angry and went into the earth.
I will suggest the reasons:
1. With her single curse, she can kill ravana
2. With her blessings, she made the fire as ice to shri hanuman
3. With her bliss, she even atlast blessed the srilanka and departed from there
But she just waited for Rama, to show his powers and this shows her simplicity... The prize won by simplicity is ...????????????
