I think there are people who feel a strong impulse to cause pain. Subjectively, it may seem to them that they simply didn't think of a non-pain-causing method of achieving their other ends. For all I know, at least some of them feel causing pain as a relief of anxiety rather than pleasure.

Also, it's possible to frame just about anything as punishing defection. I've been seeing some indications that a lot of bad behavior is punishing people for claiming more status than they are felt to deserve.

Or, for something milder but closer to showing a terminal value, try this.

I'm not sure about this terminal value thing-- if someone is causing pain because they feel pleasure from it, isn't pleasure the terminal value?
