I doubt he thought she'd out and out commit violence. He clearly wanted to rattle her and knew she would react. He made genuinely valid points in the CR - and she shot herself in the foot there by showing zero remorse and continuing to justify her actions. But then BB played him by making him decide.
See if instigation is wrong - then it needs to be so for everyone. You can't say for some ke poking is part of the game, and for others ke it's not. Aise toh Priyanka also told Ankit ke she pokes people knowing they'll react - and if they haath uthao, toh they'll get evicted - mujhe kya.
I think he's going to be bashed because of the political angle. And the fact that he instigated using outside matters. Warna plan karke poke karna is no new thing - and it's literally Archana's whole game.
Personally, my view is that while it is part of the game - it depends on how far one stretches it and how low one goes. What's not ok in any instance - is violence.
This is genuinely what i was confused about. It seems shiv knowingly provoked her as per his plan.... But how is it different from when archana gets up in the morning and instigates xyz as she wishes?
Is it because of the group thing that makes it more sinister and is almost like bullying and ganging up on one person??
