many wayAnurag & Prerna are responsible to making Sampada turning into an evil woman.
Sam's point of view was right in way that Anurag was responsible for taking care of Prerna & Bajaj's relationship. Ok worrying abt Sneha & prem makes sense, but y does he have to interfare in bajaj's family all the time, for e.g he was suspecious abt Tushar's past and went out of his to find the secret/
When bajaj accepted Prem & sneha as his children then its his responsibility to take care of them, Anu runs to their house when prerna says Anurag tum foran ajao.
Prerna knew that Sam & Anu marriage getting ruined, coz of her, then y did she continued to call anu and maintained friendship with him.
Anurag neglected Sam alot and he knew she didnt like his interfarance of him in bajaj's house, then y didnt he listened to her.
Cant blame Sam for being jeolous and hatred towards Prerna!
