If you give people no credit for admitting they were wrong or give them no chance to atone, then you give them no reason to do it and they will continue down the path they are on. To me it is preferable that she stops being toxic vs her continuing if those are the two choices.
I am not saying she should be forgiven, but if she is genuine, and that remains to be seen (she has a lot of work to do to prove that), then continuing to punish or otherwise vilify her, sends her the message that she's damned is she does and she's damned if she doesn't so why not continue being toxic. Why should she try to be better?
If she continues to atone and does some very positive things in future (again doubtful) there should at least be some consideration given that she may have changed.
Yeah the logic always stuns me.
"If I vote for a Democrat they'll probably take some of my money through taxes and I'll be poor"
Trump wins and ruins their business, they lose all of their money.
"At least I'm not poor because of evil Democrat taxes"
They have truly been brainwashed. Whatever bad shit republicans do they still believe the Democrats must be worse, because the republicans told them so. Even though the republicans have provably been lying to them for years.
