I think her belief of what being "held accountable" is is just people being mad at her, which it isn't
simply admitting she's in the wrong isn't the problem, it's her stubbornness to still try to be in the right and her extreme defensiveness
you want people to forgive you? APOLOGIZE TO KAT AND SHUT UP
stop getting defensive
stop giving examples of why you did it
just say
"I was wrong and I'm sorry"
and say nothing more
your side of the story does not matter bc the action still had the same affect
