Revenge is a mostly human behavior (I am loath to call it “uniquely” human: who knows, maybe there really is a killer whale like Orca, who chased and eventually knocked Richard Harris' brain all over an Arctic glacier, because the latter killed his pregnant mate. No idea what movie I am referencing? Can’t say I blame ya). Animals retaliate but do not dwell on the feelings of resentment, the sense that an injustice was done to them, the way humans do. An ant colony fights back when it is invaded by other colonies. However, when they lose a territorial war, they either get exterminated or absorbed into the winning side's community: there are no “buts” about the outcome. I doubt a soldier ant goes after the queen ant of the invading colony in a suicide mission of avenging her own queen, or deaths of her sister larvae.
