This is it. If you Google Andrew Carnegie, he’s listed as a philanthropist who built libraries. If you Google the Battle of Homestead, you can see how people literally died to fight for labor rights against him. These people were never good people. We just forgot the bad.
I’m EXACTLY the same. You don’t need to atone. I own up to my mistakes. I admit I was wrong. People see it as character development, so don’t be ashamed of your story. Own that shit! You have lived and grown! That’s very good thing.
