What Am I?

I thought by now I'd be more than a lost cause But I won't I thought I'd stop harming everyone around But I don't Am I a trail of darkness led by the breeze? If happiness is the cure, am I the disease? Am I the disease? Am I a trail of darkness led by the breeze? If happiness is the cure, am I the disease? I wish death was not all I bring Cursed be my hands and all I see Am I a drop of peace in a sea of conflict? Or is my existence pure dust to be taken by the wind? Am I the Evil that goes against your preach? Will I be a better help when I cease to exist? What Am I?
