I am thinking from Bharat's point of view. I think if my mom said that she has changed but she was completely like Sindoora before I would believe that she had changed and I would forgive her if she promised she would never murder anyone again. Almost everyone has a soft spot in their heart when it comes to their mom. She's the one that gave birth to you and it would be hard to believe that she's lying even if she was like Sindoora before. I think I would personally forgive her if she said she had changed, but if I found out she hadn't changed I would tell her to leave and maybe shoot her again.
