as protrayed so far sultan may be a golden hearten don,0ne who respects women feeling, father of a adorable son so and so does this alone sufficient enough for a mother to support her daughter to have a friendship with a person who is most wanted criminal in eyes of law and scoiety. if she has so much concern for her daughter the she should also restrict her daughter from having contact with sultan also.
i agree intially she was against madhu for supporting sultan but after holi she also started to support a don hearing his motherly sentiment story . each and every criminal have their own background stories for going against law and society even then a criminal is a criminal. if her daughter is having friendship( or what ever name u call) with such a person will she be respected in the society (in reality no), her dignity and character will be put into question and also as per law she is supporting and protecting a criminal she is also wrong in eyes of law .
if padmini has really taught her for always fight for right and wrong. then she should not support her daughter for protecting a criminal (even its for sake of aryan as coated by madhu) and still maintaining some relation with him becaz in this case also her daughter future will be in big trouble if law comes to know about her contact with a criminal she will be arrested and take to jail also. not only her respect ,character but entire family's respect and dignity will be in question. it will directly affect not only her and also her sister trishna's marriage and career also.
act of going back to rk by madhu will affect only her future but maintaing friendship and supporting sultan entire family will be affected.
so from my pov if paimini is angry and diowns madhu for going back to rk she should be show same angry concern worry and disowning madhu for having friendship with sultan also. as per current track and protray of both characters(rk and sultan) both will create trouble in her life. but damage caused by sultan will be little heavier for a person like madhu who loves her family to the core she will be fully broken becaz of her act if her entire family suffers.
