I think we all have our sadistic/masochistic tendencies, but we channel them from different places. Some want to bleed and kill, some want to fuck and fight, some want to play the martyr or tyrant, some need to bring others low to feel high... and then there's those who think they deserve eternal punishment so maybe they'll feel clean. They need to suffer to feel worthy, that they've earned it. Then both of those polarities have gunned for those souls who know and long for equality, for freedom and for truth. In both darkness and light it's easy to be blinded, but those who walk at the twilight and the dawn see the truth of both and move between with ease.
