The transformation of a hero to an anti-hero will always remain one of the more interesting character arcs in any storytelling process. Such a reversal also, additionally, muddles the conventional boundaries of good and evil, thus forcing an audience to reassess its notion of morality and justice, or even the human condition. These are gradual shifts that often turn a loved protagonist into a much darker, more complex one, mirroring the complexity of any real dilemmas where right or wrong is always blurred. It is for this reason that such arcs appeal to audiences, not because they are unexpected, but because they reflect the inherent duality within us all.
