Whether anger causes pleasure?

Objections

Objection 1 : It would seem that anger does not cause pleasure. Because sorrow excludes pleasure. But anger is never without sorrow, since, as stated in Ethic. vii, 6, "everyone that acts from anger, acts with pain." Therefore anger does not cause pleasure.
Objection 2 : Further, the Philosopher says (Ethic. iv, 5) that "vengeance makes anger to cease, because it substitutes pleasure for pain": whence we may gather that the angry man derives pleasure from vengeance, and that vengeance quells his anger. Therefore on the advent of pleasure, anger departs: and consequently anger is not an effect united with pleasure.
Objection 3 : Further, no effect hinders its cause, since it is conformed to its cause. But pleasure hinders anger as stated in Rhet. ii, 3. Therefore pleasure is not an effect of anger.
