Reminds me of one of the most goody two-shoes paladins I ever knew. I had a character who was the most annoying prick I ever played, and I specialized in those. I knew something the party needed to beat the big bad and lorded it over them and especially mocked the paladin, who really wanted to kill me but couldn't.
Because of an accident, the party prematurely found out what my character knew that they needed. This was supposed to happen, but later, but anyway, the paladin was commenting darkly that there was no particular reason for me to be alive any more. I taunted him about how totally not good and not lawful it would be to kill me.
He ran me through with a sword on the spot. He wasn't that kind of a paladin. He was the cool kind.
And everyone stood and applauded. (They actually did including me.)
