Manvi did everything she could for her survival. Her single biggest motivator for survival was her thirst for revenge. The show is not properly delineating it ( due to constraints as a result of corona scare) which is such a shame. Come on, in the real world, completely normal people take bribes and game the system. That does not make them sociopaths.
It still makes you a criminal. Here Vikram is a lusty creep. But Maya would've cheated him even if he was a nice, normal guy. That makes her an equally disgusting creep.
