AITA for getting my r@pests children taken away from them

I (15f) was SA by (20f) 13 at the time when I was 7 every week until I turned almost 9 and learned in school that what she was doing to me was wrong and finally told my mother what she was doing and she stopped having sleepovers at our house but she was never actually punished. When I was 11 I was SA again by (19f) 15 at the time this happened used to take me into her room "so we could play" and would make me strip and would touch me this happened until I was 12 and her mum walked in while she was touching me and I was crying and all her mum made her do was say sorry both of them basically got away with what they and and now at 15 everyone in my family acts like they did nothing wrong and they come over to my house and everything they even come into my room and I just want to cry recently both of them have had children and come over to my house showing off their kids and how good their lives are while I'm still in therapy from what they did to me and it made my blood boil so I called up the local child protection service and told them what happened to me and that I think they are a risk to their children and that I was worried for their kids (20f) child got removed from her home and is now with another member of her family and the same for (19f) and I also privately messaged both their baby daddy's what they did to me and both their baby daddy's now are fighting for full custody of their kids and I don't feel bad about it at all they come over to my house crying to my mum about it all and I can't help but feel happy about their pain. so am I the asshole?

Edit: I didn't just do it to be vengeful I do have genuine worry for their kids I don't want what happened to me to happen to their kids aswell and I've seen the way 20f has treated her siblings and she can get quite abusive and I've seen 19f take her anger out on a child more then once and she has screamed at her baby for crying before so I do have genuine concern for those babys
