Stop encouraging people to "forgive"!!!!! Uhh he raped him, RAPE. His biological half brother!! This is not a situation to wish him happiness. Instead go and tell his mother what he did so he disgust her as well.
Fr. People mostly say it helps to move on with your life. But seriously, you can achieve peace within yourself and move on without forgiving them. What you need to do is not forgive them, but make it clear to them and yourself that you were just and not in fault and hope that someone else doesn't experience it.
Why forgiving especially when they aren't even that interested and invested in redeeming themselves?
I cried so hard bro wtffff
