Since Maya's childhood, Maya was never accepted by the society. She was isolated and been called mad and bad due to which she was demoralised. Its not like Maya had no empathy or sympathy for people. She was good before, she did have goodness and would go extreme to save other lives. BUT..
What went wrong was Maya's good deeds were all IGNORED.She even desperately tried to be accepted by VM. BUT..VM and others didn't give her that ONE CHANCE.Had Maya not left her true friend Lord Ganesha, then Maya wouldn't have turned so bad as she is now.So my point is people like Maya need to be given that one CHANCE/OPPORTUNITY.Maya's life experiences i.e. her isolation from the society made her loose all that belief in humanity and goodness. She even left her her true friend Lord Ganesha out of anger and hurt. Hurt of loosing her unborn child.People like Maya need support and encouragement. There has to atleast be one person to guide people like Maya.In Maya's case Arjun failed here because instead of guiding Maya or trying to make her see sense at an early stage, he succumbed to Maya and then when things went out of control he started to behave extremely rude and insulting to Maya.Now I think Arjun has finally realised how to handle Maya. He is guiding her now... but lets see whats the outcome of this... since its a bit too late..Saanjh on the other hand is similar to Maya in terms of her obsession with Arjun. When the show had started the symptoms and behaviour of Saanjh indicated obsession. The way she used to cut Arjun and Maya's pics when they were not even lovers indicated her beyhadh obsession for Arjun too.And then all that applying vicco turmeric on ArYa's haldi day and other rituals just strengthened this indication. We shouldn't forget the tamasha she had done on ArYa's wedding day either. Any normal girl in Maya's place would have lost her senses there. Even after ArYa's marriage, at the early days Saanjh still did some more tamasha with Arjun which made Maya all more INSECURE.Therefore had Saanjh been Ashwin and Jhanvi's daughter and had she experienced the same thing as Maya i.e. insult, ignorance, isolation and her husband having a friend like Saanjh herself then Saanjh would have more or less turned into another Maya. And this new Saanjh (Saanjh Mehotra) would have definitely hated Saanjh (friend of her husband) as Maya does. Hope I made sense though... lol
