Sakshi was orphan. Nirbhaya rapists did have families.
Sakshi had no guidance. And she grew up among shady people as she describes how she knew about gambling since childhood.
Mindset is definitely one thing. But circumstances cannot be ignored.
In most stories a lone female mostly is shown aggressive, threatening and even deviant for survival. That Amma ji in Laado serial was also gun toting lady don. She couldn't have reached her position or kept safe as a lone woman with kids unless she was aggressive.
It's a defense mechanism. Otherwise girls alone on streets suffer unimaginable abuse and even lifetime slavery. Unless they luckily come in contact with NGOs or good samaritans who educate them and keep them safe.
I will not compare Sakshi to Nirbhaya rapists because they raped for pleasure. Sakshi in this show never kills or abuses just for pleasure. It is always to protect self or others. I am not saying it is right. But she is not like Shaurya who maims for pleasure.
Nitya suffered but bluntly she is also using illegal means only. But yes she does not kill and still has conscience because she had guidance of family till she grew up and still has guidance in form of Dayal who keeps her in check.
Sakshi had nothing. The shady circle she grew up in, she took to their jungle ways. She entered a family deliberately by blackmailing Raj. And Raj is not family for real. They are family on paper.
Considering he too hates her and somehow wants to get rid of her, get those tapes etc so Sakshi has to be suspicious at home too.
I can understand why Sakshi is the way she is. But I do not justify her nor do I think she should be spared. She deserves punishment. And her life in many ways has a punishment only which she will realise one day given how she has nothing.
BTW why do you single out only Sakshi? What about Rajnath Goenka who kills, threatens at drop of a hat? He did not even have such bad circumstances! Why is he given sympathy?
What were conditions of Raima ji who has happily partnered in every crime? And even dropped ideas in minds of Goenkas? Who first got married to Jatin and then kept bashing and blackmailing him through Goenkas?
Others are worse because they do not even have lack of family, poverty etc as an explanation for their deeds. They were well off yet still criminal in their tendencies. They cannot be compared to a girl who grew up alone on streets and was so deprived that she had to steal from a dog.
Sakshi lived among criminals and animals, developed animal survival tendencies and will die like an animal.
