There are several layers to each character . On the surface it may appear that Satrupa is ruthless. She has to adopt a tough exterior to stand up for her rights something she has to do on her own. The men in LM have been selfish and mean to others. She has to stand up for others. Satrupa did not have time to win over Anami by gently coaxing nd manipulating her like Sudha. She had to use force to ensure that power goes to the right hands.When one is involved in creating or preserving something one cannot hand it over to someone heartless like Avdoot and thereby to Pujan and Kamini
Sudha had used Narotham 20 years ago and she is using Anamis vulnerability and Narotham to get to Baldev. She does not have care of finer feelings for anyone.
It is indeed very kind of Satrupa to have kept him in LM and not sent him to some boarding school where anyone in her position would have.
In the unravelling of Satrupa and Narotham we will get to see the tough perspective but kind approach. She definitely is getting him to see other options in front of him. Just as she initiated Anamis thinking her words and actions will make Narotham think and make his choice wisely.
