I completely agree. Not only Rohan but all those who are involved (his family, wife) should be punished.
But there's another angle to it. Shouldn't Sheela's family be more cautious. Agreed that Rohan and his family are criminals but Sheela's parents and brother weren't born yesterday. Shouldn't they be more careful - considering this is an arranged marriage and they know nothing about the family - with a little background investigation, divorce papers (of Rohan) and such stuff. No, the whole family is blinded by expensive gifts and sweet talks. There are cheats and criminals in this world and everyone has to be on their guard, esp in extremely important matters.
Sarita tried to expose Rohan - the family does not think too highly of Sarita's character but shouldn't they be a little worried and try to find out if there is any truth in her allegations?
Also, Sheela is in love with Rohan and ready to die for him . Like, really? I read in WUs that a couple of days back she was crying when Rohan made some physical advances towards her. It's not like Sheela just felt shy or nervous - she felt disturbed and depressed (hence the crying) and that's not normal in any courtship as far as I know. Even in retrospect, she didn't remember those moments with smile but with tears. Shouldn't that alert her to Rohan's character? But no, she choose to believe Rohan over her SIL whom she has known and supposedly loved for 10 years.
Sarita should forgive her MIL / FIL as there was no such relationship they shared that they have betrayed by not trusting her. But she should not forgive Sheela for not trusting her.
