Very nice discussions are going on.
As far as I can see, Kaikeyi is not trying to remove Ram and replace him with Bharath on the throne but she is trying to punish that MAN who insulted her feminity and also of her 2 sisters. She was not interested in making her biological son the future king but she is adamant to teach a lesson for that person who forgot to stand by his words. She is not forcing her queenly rights on Ayodhya but is trying to avenge that person who called her maternal home as a threat to his family and dismissed her brother like an insect on his plate of sweets. She very well knows that whatever she is doing is wrong but the hurt induced by her husband of whom she had loved through out her life is so deep that even this revenge looks too small to her. She is trying to remove RAm from the race for the throne for a simple reason, Dashrath, her culprit loves him immensely and even a small scratch on Ram will hurt Dashrath and she has taken a slow and steady route to induce pain to her husband, the father her son who went against the belief of people on his Vansh as " a Raghuvanshi will always defer to his words" by turning his back to the words he had given to her father. Had Dashrath told her the truth about his promise to her when she questioned him, she would have accepted that ram is their elder son and he shall succeed. But the way king Dashrath behaved in a knee jerking way by dismissing her brother with a threat and then diminishing his wives (all the 3) as nothing and his sons would have been born anyhow (as if even without his wives to bear them in their womb) was too harsh. Added to this she still think on the betterment of her state and its people and that is the reason she ensured that Bharath is properly trained and attained the capabilities required for a King, so that in her bargain with her husband, Ayodhya shall not be affected by having an inefficient ruler. She could not compromise on the quality of a Raghuvanshi king, hence she made up her mind to paqrt with her son for 8 long years, so that he is in par with her son Ram, and could rule the state even in the absence of his brother. She not only ensured him to learn warfair arts but also ensured that he is not dependent on his elder brother for all his moves. kaikeyi didn't forget her duties as a mother and also as a queen. All her acts were of an wounded woman whose existence was questioned and hence is like wounded tigress who is waiting to avenge her prey and here the prey is none other than her husband. To teach him a lesson for life, she doesn't mind, if she has to hurt her sons and sisters in that process.
But the case of Chandrabaga is totally different. She was never a queen (in real sense) to begin with nor she had undergone the pain of a peasant who suffered due to drought for 12 years, Being a royal family member (wife of the prince), she had no shortage on food or clothing's and water. So doesn't know the meaning of famish or starving. She might not even have been affected by not having kids as her main aim was to become a queen. So Sita's birth had not affected her so much as it affected the peasant lady. While king Dashrath gives 100% credit to the puthrakameshti yaga for the birth of his sons, Chandrabhaga may not give that credit to Sita immensely. However, just because she thought of her daughter's marriage point that she doesn't love Sita or she doesn't treat her as her daughter. her worry is just that every human on the earth may not treat Sita as a child given by GOD or mother earth. If Rajashri Janak sent people to search for Sita's parents (claiming that a child wrapped in fine cloth can just arise from earth on its own) so that the child be handed over to them, we can't expect others to think her as Devi or something. So during the alliance matching, for sure people will pin point her birth details and say that since her origin is unknown, show reluctance to accept her as their family bahu. easy to say than done. That is what she expressed here, about her doubts and not her intolerance. And who knows, if not for maharishi Vishwamithra who made Ram participate in the Swayamvar and fixed Sita's alliance with Ram, even king Dashrath would have raised his apprehensions. Even in today's world it is difficult to get a match fro an adopted child into a respectable family, if the child was adopted from some NGO or adoption Centre and not among the family. So it was expected at that era.
In case of
