My cousin is a pedophile

He's 20-21 and in a relationship with a 15 year old girl. Everyone knew. Her parents, his parents.
Now she's pregnant.
When she went to the doctor to check, they reported the case.
I'm so glad it happened but I still feel so bad for her.
In two days they planned to get engaged and married at the same time. I hope it doesn't happen and the police do something about it but I feel like he's gonna get away scotfree.
She's his sister's classmate! It's sick.
I suspect one of my uncles is also the same.
I'm surrounded by pedos.
