More than Sanchi it is the senior Shekhars who need to be blamed for all this.
Sanchi may have taken a liking for Jagya whih is more to do with her young age.She has seen the side of Jagya which was very attractive and sensible and dashing so one cannot really blame her for falling for him.
But if she had been taught to think about the consequences of her acts she would have never behaved the way she did throwing herself at Jagya and insisted on marrying only him behaving rudely in front of the people who came to her house with a marriage proposal.This is all because her parents never bothered to teach her lessons which were needed.
They just gave into her demands and took the easy way out whenever she threw a tantrum.If they were in a bad mood they would just shout at her other than that they never did anything to control.
She may have been a more difficult kid but that is no excuse.If they had been tough with her whenever it was needed and put their foot down when it was necessary from childhood onwards it would have never happened.
It doesn't look like the senior Shekhars ever actually sat her down and talked to her like she is an adult.
They are either too busy doting on their doll when they were in a good mood or too busy getting scared that she would break if they did not give into her desire or when they were at the end of their patience they would shout at her.I don't think their actions and reactions with regard to Sanchi have ever been balanced.
Now Sanchi will be faced with all the consequences of her mistakes and hopefully ends up learning something from them.
Her parents have to sit and watch her pay for all those mistakes.This is the price they will have to pay by not putting in enough efforts in raising their daughter
This is what Sumi and Bhairon and DS did with Jagya too.No doubt they loved him a lot and cared for him.To counter the pampering done by DS Bhairon was extra strict on him and sometimes very harsh and Sumi was a bit more balanced but she did not have much say.
As a result Jagya grew up to be a spoilt brat who was only scared of his father.
There was never a scene showing Bhairon sitting down and explaining why what he has done is wrong. When ever J misbehaved he was only punished and was not explained the consequences of his acts.By the time Jagya grew up he only had fear for his father.
Once he became indifferent to the punishments his descent became accelerated.
What he should have learnt at a young age from his parents and elders he had to learn from life.Now he is a man driven by feelings of guilt.If they had been more patient with Jagya they would have ended up with a son who is sensible.Anandi could always see him reason so I don't think it was so difficult for Bhairon or Sumi to make him see reason.They did not teach their son how to be a good husband and they ended up losing their DIL.
The failures on the part of the elder Singhs and Shekhars are pushing Sanchi and Jagya into a disaster.I only feel bad for both.Sanchi is foolish and blind doesn't know where she is going and falling into a pit Jagya under the burden combined guilt of his and his parents is being pushed into the same pit as Sanchi is falling into.
The only sensible people are the younger generation Mr and Mrs SRS,Jagya and Mahi.The elders who are supposed to be guiding the youngsters have gone blind.
