I agree with you S... Rashi isn't even close to redeeming herself. Funny thing is, she isn't even thinking about it. She has a blatant disregard for human life, feelings et al. She is too materialistic and needs to grow up.
She is the educated one, and not has she ever used her head like an educated, thinking, modern individual that she portrays to be. She has allowed herself to be used by her mother and her baser needs as a brainless twit..
She is just sorry for her loss coz now no one cares for her.. she had Jigar n Hetal before but now she is all by herself.. She is indifferent about Hetal but Jigar was a puppet and she misses him fawning over her..
She is still very shallow in her thoughts, take for example the scene at the temple when Jigar gave 100 bucks to the beggar and she wanted 90 bucks back. That was disgusting.
I find no remorse in her infact its just the opposite, she hasn't done anything willingly. Had Ahem not saved her by mentioning shock treatment she would have been in Rajpal Nagar, a place which she deserves and belongs to.
She is just playing along and wants Gopi/Gohem to fix her problem (Jigar) so she can be Queen Bee again and flutter around. Jigar is too sweet to be taken for such a vicious ride, the second time around.
P.S. - I am not anti-Rashi, this is my POV.
