They will never redeem him.. That's the crux of the story..
He may ask cn to let shruti live in the same house or let him marry her.. Because that's his new masumsi zimmedari...If you notice his dialogues there are no sign of redemption.. But they made him more hateful.. Sai is independent that idea irks him..so he doesn't want someone who will never satisfy his ego ..
It will be good if that paves a way for solo journey of Sai.. She will cry for sometimes but will be completely over with him..
I'll be more than happy if SaiRat don't end up but I don't think they'd do something like that at that point. I mean they can make Virakhi endgame for real life couple but why with Shruti. They can easily kill Samrat off any point.
