Hi see,
No, you're not a bad person. We don't owe abusers, especially those of our families of origin, anything. But I have learned they can hold us captive to the pain if we don't free-willingly let go of them by forgiving them and their deeds, even if they don't ask, and even if we don't tell them we forgive. That way, we free ourselves of the attachment to the memories of abuse, but gradually.

Maybe later you will develop a relationship with your brother and through his experience he might ask you for forgiveness.

In my experience, family members who have wronged me and later interfered with my own kids, have never owned up to their messed up dealings. I tried to invite my sister to therapy in order to discuss offenses, but she always had an excuse.

Visiting your brother is a pretty nice thing in itself.

Peace,
