R dadi and dad have guided her in the devotional path but failed to guide her as a person, dadi knew she was infatuated with Mohan but sill left her in Trivedi mansion the first time she went to see her there. Radha appears to be a stubborn person by nature who does what she wants using the Gita/BBji idols without realizing that carrying them around is not as important as following what has been taught. She did all the things which Gita did not teach her, run away from home, feel infatuated with a married middle aged widower with a daughter and then achieve all she wanted through lies even if her intentions are to save Mohan/Gungun from Damini.
The writer should have concentrated on Radha's characterization which would have made watching the serial for Shabir's sake more worthwhile
