They are not following dharma who resort to violence to achieve their purpose. But those who lead others through nonviolent means, knowing right and wrong, may be called guardians of the dharma.

Monks, when ignorance is abandoned, and knowledge arises in the monk, with the ending of ignorance and the arising of knowledge he clings neither to sense-pleasures, nor does he cling to views, nor to precepts and vows, nor to a Self-doctrine. Not clinking, he is not disturbed; not disturbed, he attains individually nibbana.
