Then what of "self-preservation"?
In adult age, I avoid potentially dangerous situations from a legal point of view. I hate people and want to tell them but if I did too openly I would be prosecuted.
However, I do talk down to people, humiliate them, behave rude and arrogant and make people feel insulted, guilty, apologetic etc whatever. If I had met Callaway and her children IRL I would probably have just bought the last bag of candy in front of her daughter, the one she was pointing at and yelling for, and then when I got out of sight tossed it in the trash.
A favorite pleasure of mine is talking bad about something in general, when people who can probably strongly identify with that subject are sitting or standing near me. For example, I can trashtalk ginger people in a loud, arrogant voice if there's a family with two ginger kids nearby. And I pretend that I didn't see them ofc.
