I think shrenu is a grey character so we cannot justify jhanvis actions with Kavya, arush and Dhruv. Agree injustice done to her isk MATLAB yeh Nehi ki whatever she does is right. To achieve her goal she has hurt innocents that's why I said she can be redeemed.
Hurting the innocents voluntarily is an offence. But hurting them for protecting ourselves in not an offence.
