Of course she's sorry she'll lose her job. I'd venture she's not sorry, nor does she regret, being a total douche. I wouldn't hire her to clean toilets with that attitude. What happens if one of her patients expresses some opinion with which she doesn't agree?
No matter what phrases she parrots about "I should have protested peacefully & I didn’t, & I regret that. ‘I’ve let myself down & I do understand that fully", I sincerely doubt she even understands that she was wrong, or WHY she was wrong. I mean, look at that so-called apology. Nothing about "I harmed an innocent old man" or "I apologize to him and I'm sorry I hurt him". It's all "me, me, me". "I didn't protest peacefully, and I regret that. I've let MYSELF down." No, you narcissistic tub of suet, you ABUSED AN OLD MAN. You acted like a violent, crazed savage OVER POLITICS. You're a bad human being. That's not "letting yourself down"; that's not having any expectations of yourself in the first place beyond your own whims.
Learn to fake remorse better.
Although looking at her picture, it's pretty easy to tell that she and self-control are total strangers to each other. That's right, I went there, and I regret nothing.
