It is the non-standard temporal axis that builds up moral ambiguity. The paradoxical power of time is transforming the borderline between "good" and "evil". By a somewhat simplified definition, this is an image of certain events in the past that can or should only occur in the future, which, in fact, is a goal, an obligation, but not a reality of the past. As a result, good turns into evil, and the other way round.
Did you ever observe other characteristic powers of abnormal temporal axis?
