Should I be worried about the new woman my dad wants to date?

My dad has been online dating for just over a week now and well, he’s very desperate and not a very nice person either. I’ve been dealing with his mentally and emotionally abusive behaviours all my life, I know he’s not cut out for romance and basically watched him and his ex partner just use and abuse each other but he was going to get out there at some point yet I am concerned for the new woman’s well being.

He said something that made me rather concerned earlier, they’ve been talking since yesterday evening and he said this today “she puts herself down a lot already and that’s a good sign because that means I can swoop in and be the good guy with the compliments and all that stuff” to which I replied “uhhh, that’s exactly what a narcissist would say...” he said “true haha” and he straight up has narcissistic personality disorder, there’s no doubt about it but do I have any obligations to tell this woman or warn her if something starts up between them or should I butt out and let her take care of herself? I worry because a lot of women have gone very mentally ill after meeting and dating my dad for a while, he’s very draining, nasty and well everything of a narcissist. I don’t want to watch another woman get broken but also don’t want to over step my place?
