You nailed it Leaves!
If one is supporting wrong doers one cannot get good friends.
Sakshi often reminds me of Sanjay Dutt in Khalnayak in a way. He was ruthless due to what he suffered in childhood and had totally misplaced sense of loyalty to his boss Roshi. For him either there was no love or emotion at all or an insanely possessive animal like streak. He got his own mother kidnapped when she sided with his rival!
Sakshi has similar animal like view of life. Kill or get killed, beat or get beaten, fight over territory and control.
That said she does worst things for ones she loves or favours. Till now she killed only to save Shaurya. It makes me think she killed Rehmat Khan also for someone else and not just of her own accord. Either she was ordered to do it or did it for revenge herself or for someone she loved.
She calls herself sherni. Forgot to live like a civil human. Forgot that lions often get hunted and caged.
I find her as self destructive as destructive she is to others. The way she spurns Suchitra, snubs Kangana, bashes the same Rajnath whose name she cashes on...she just alienates everyone from her. Then lies alone in front of the mirror or plays piano!
Her blind love for Shaurya ruined her. He knows his mom doesn't give that much leniency to anyone except him. And has he exploited it or what! For him Sakshi ignored morality, married life, personal life (she is always sensing danger never relaxes), daughter - just everything. Strange love is this that it didn't even lead her to teach values to son.
I guess Shaurya was the first one in her life who she could truly call her own. She had no one earlier. Marriage with Rajnath was a deal. Or maybe she was hurt in love. Her baby was the only one she could truly attach herself to. And being male plus first born he got lion's share of attention. Shaurya took this all for granted.
I am interested in knowing story of this complicated woman and seeing her brutal end. I want her to break down and reveal all dirty secrets of herself and her family before she lands up at the same asylum she sent Payal to.
After her maine bhi pyar kiya tha dialogue I feel she was hurt in love this is why went back to ruthless sadakchaap ways, enjoying power and attention by inducing fear in others.
