Wish Granted! You die honorably. Unfortunately, because the world has become so morally ambiguous, no one cares and someone writes "Fuck you" on your tombstone and then proceeds to piss on it. Oh, and your family, which has secretly been evil all along, disowns you after your honorable death and denies your existence, as does everyone else. You fade into anonymity.
I wish for the power to shoot death beams out of my eyes that cannot kill me.
