I agree. I also don't think Ragini could ever be redeemed. That false rape allegation was the nail in the coffin for me. Not only did she try to murder her sister, but she broke up her parent's marriage, emotionally blackmailed a guy into marrying her, attempted to ruin SwaSan relationship with their family, and get Sanskaar to go to jail by mocking a serious issue in india - sexual harrassment. She's just gone too far to be redeemed. There's no redemption there.
Speaking of redemption, I also don't see any redemption for Shekher. He's just a horrible man. I'm hoping Shomi has seen what a spineless, horrible man he is and stops loving him. She deserves so much better. Currently, all the male characters (save Shekher who cannot be redeemed and DP/ Sanskaar's dad who are justified in their actions/ stances) all need redemptions. But whatever, the men aren't even supposed to be central to this show LOL.
I'm like 80% convinced this show is going to end up like Uttaran with one sister being evil, selfish, and conniving and the other sister being a self sacrificing idiot.
