Was SA'd at 10yo by my brother and now i want him locked up

Location: Portugal

When i was 10yo, i was SAd by my older brother (16 at the time), at the time he didn't suffer any major consequences, just some community service for what i've been told, they said it was bc he was young and it was his first time commiting that offense. Althought i was supposed to get therapy at the time to deal with the trauma, but that never happened. I only started therapy 4/5 years after that. I'm dealing with depression, and tried to kms 4 times since that, did a lot of SH and been suffering since then. It´s been now almost 8 years since my SA, it enrages me that i´ve been suffering so much, that my innocence was taken from me and he didn't get a deserved punnishment. He now has 2 children, a toddler and a baby, i thought he would've grown, i would've atleast forgiven him if he gave those children a good life, but, he is a fucking drug addict, has punched my aunt and threaten my grandma for unknown reason and me and mother are having another legal battle with him and my sibling bc of my dad's inheritence, he died almost 2 years ago of cancer, he left everything prepared so there wouldn't be a fuss and fight, but they aren't doing their part of the deal established by my dad, and now i got the news that they are all living in my father's house (which we inherited and they where supposed to sell the house if they couldn´t buy it, which they can't, also im not welcomed there, cant even get the picture of me and my dad that if had given him for his bday), the house is a total filth and those children are having to live there, no one does anything and i'm worried for my nephews. Can i do anything? I want that piece of shit behind bars or atleast get the kids out of there.
