My father was recording me and her wife knew

I am a Female in her lates 20. My family found out that my father was putting spy cameras in the bathroom when we traveled. I have been dealing with this with therapy and my family support. We cut ties with him. However, I found that his wife knew what he did for over 4 years. She used that information to blackmail him. When she was confronted, she thinks I am responsible for what he did. I feel sick, like my father needs therapy ASAP but his wife is pure evil. I feel like he is receiving the karma he deserves as he is scared of getting processed by the police and that everyone around him is leaving him. But I’m my opinion, she is not getting any karma on her side. I want to publicly tell everyone what she also did, but I feel like that is more revenge than karma. I hate feeling like this, I don’t like to be negative and do wrong things, and doing that feels wrong. How can I deal with these feelings? I feel like everyone around me is treating me like I will break at any second, but I don’t know why I feel that what she did is worst than what my father did
