If there is 'no-self' (or anatta), then do our actions really matter? Does anything we do really matter? "who" cares if I be mean to someone or go around killing tons of people? In the grand scheme of the universe, these actions, and their effects, wont 'mean' anything, and no 'one' personally is effected, since nothing has a 'self' anyway....
Going around killing is done when there is "I" in the mind

When the mind is empty of Self, there can be no selfishness, no vengeance, no anger or hatred

Only selfless kindness and peace
