Sanchi is his Iago.
And also Dhritarashtra syndrome. Not wanting to see Sanchi's evilness and his mother's vengeful attitude.
From well loved hero he is becoming tragic hero caught in the web of family love, family politics.
Anandi sees everything and she is also in awkward situations due to her new responsibilities towards her new family and she has tremendous patience to make Shiv understand the consequences of taking on singhs who are like mafia don Godfather family.
Sanchi who is the root cause of all this, will destroy many lives, not only that of anandi and Shiv.
Anandi's is already destroyed and shiv is on his way to self destruction.
I can see impending doom.
