Let me start by saying that I don't think Vikram was ever in love with Maya but just obsessed.
That can be clearly seen from the way that he said that only he can win Maya or gain Maya, when she first wakes up..
No one becomes a psychopath just because someone leaves them..
If he was a normal person he would experience normal emotions to betrayal, like anger and sadness...BUT all this guy wants to do is complete his SR...
He was a creep, he is a creep...end of.
