Vikram had been silently supporting her in all her kaands and she landed up in baby swap. Nothing (stealing money, murder attempt/accident on Chathuri, baby swap) seems to be wrong for her if it serves her purpose. In reality, baby swap is a big crime and even doctors and nurses are punished if they are found out. Then, why is the legal system not pursuing Meena's case now. It does not seem like Vikram had taken the complaint back and Taisa also has the right to make a complaint.
The CVs have cleverly diverted the baby swap issue to domestic violence against Meena and RM supporting her is like again encouraging Meena more. She will definitely do and is doing more kaands to get her way.
DABH was unique and there was clear end/revelation/punishment for most deeds (some issues were left loose) in all the tracks but the CVs are reluctant to do it for Meena and we viewers do not have much of an issue with her punishment too but she needs to realize or most importantly, the family needs to make her realize that what she did is a crime and she needs to change her ways.
