I love this topic and I strongly feel that it depends on the specific situation and also that "punishment" and "consequences" can be deliberately dealt out, but can be 2 totally different things. My mother was very abusive toward me, and now she suffers the consequences: Zero Contact with her daughter, and a lifetime of additional shame on top of that. And quite frankly if she died in a car accident today, I would not care, because as far as I'm concerned, she is a stranger who abused me as a child. Certainly I had no real mother.
She was not a mother. I had to be my own mom. I'm an adult now, and I exist with extreme autonomy and independence, and owe that evil crazy lady nothing. She doesn't deserve my time, my attention, or even my thoughts. I do hope she has a decent life, but like I said, I wouldn't be very sad if she died. Just stating the flat-out truth.
Now on to my father, who was also abusive and narcissistic but is now, in his old age, softening up (to a degree) and owning up to his mistakes (this is a rare miracle, do not expect the narcissist in your life to own up and make any lasting changes, and no matter what, always know that they will let you down again and again, just be grateful for the times they don't! They are too flawed to be consistent I believe).
However, because of the neglect and loss he caused in my life, sometimes I feel he "owes" me for what he took from me, and until he gave me back some of what was owed, I refused to be in his life. But he finally gave me a profound, sincere apology, he gave me back some of the time and patience and efforts to understand what he put me through, and he gives financial support for health and therapy, and although he can't give me everything I want and he still makes mistakes,
I feel he already got the punishment he deserved and has "Served his sentence" with me. Because my life has been so miserable for nearly 20 years, and I lost so much, I feel I fully deserve to take every single thing I can get now. If there is anything that I love or need, anything that makes me feel happier, healthier, and leads me one step closer to feeling like my truest, most confident, most powerful self, I get it, and I feel I deserve to have it, and I deserve to take some of that back in, for myself, because I am determined to make up for what he took from me.
Side note -- I feel anyone who sexually assaults a child deserves profound punishment, jail time being just the beginning. Death penalty should be an option for many cases. Depending on the nature of the crime(s) and psych evaluation of the person, other treatments, isolation from society, and a host of other options should be dealt out.
