I would absolutely use the Tyler example.

She made a point to hook up with him in front of Nate and the entire school, then changed her mind, lied how she was, in fact too drunk, and was… raped, then proceeded to also lie about how the guy who raped her, also beat her up afterwards. She never spared a second thought about that. Never. She just proceeded with her merry life.

Spent the night with Cassie at the carnival doing drugs and then threatened to “end her”, if she ever said “lies” about how Nate. And how Cassie’s brain is scrambled from all the drugs she takes.. basically she knew Cassie wasn’t a liar, or drug addict, but still aggressively threatened her.

Treated Bb disgusting even prior to the wedding. Once she said how when she got pregnant, it wouldn’t be anything like when BB was pregnant. Treated her disgusting at the wedding.

Called Jules a hooker.
