For the Dalai Lama, hatred can have no virtue. It only eats the person from within and poisons his or her interactions with fellow human beings. In his words, "Hatred is the true enemy; it is the inner enemy." Perhaps we can say that the feature that distinguishes anger and hatred is the absence or presence of ill-will. A person can be angry without bearing any ill-will towards his or her object of anger. The Dalai Lama instructs us to ensure that our anger, even when it arises, never culminates in full-blown hatred.
