My son turned from kind and caring to hateful and destructive, i don't know what to do.

Around 2 years ago, my then 19 year old son was sent into prison for rape, he spent 15 months in there and then the girl that accused him revealed that the rape never happend, me and his siblings visited him alot and sometimes we would get really angry, especially my other son would call him a rapist that should kill himself.Since then, hes gotten tattoos all over his body, and a couple weeks ago he got one which says 'Alone' he said he got it from some rapper that died.Before he went to jail, he was a quiet guy that kept to him self and did what he was told, went to school and while he wasn't the best at it, he was good enough. But now he's never really home, hes always outside, he's gotten into fights, hes got a big scar on his face that goes over his eyes and even on his eyelids.I'm not sure if i told all the story good for you to understand, we're swedish so i might have written some things a bit strange. Please help. via /r/Parenting https://ift.tt/2whdvCC
