They are characterized by their contradictory nature and often difficult actions. Anti-heroes continuously struggle between doing the right or wrong thing and have to make decisions of morality that come with serious consequences.
The anti-hero's conundrums often feature compelling dilemmas where what’s “right” is blurred by other considerations such as revenge, loyalty to peers, or society's expectations. Deciding on what is right is something that requires a great deal more thought than usual.
While this complexity may prove challenging to navigate at first, it makes the journey along the way all the more interesting. For example, look at how Sydney Carlton’s actions in A Tale of Two Cities transform an existence of self-pity, pessimism, and drunkenness into a hero's life.
The anti-hero's tale is one of humanity and tragedy, often leading to intractable consequences. Yet, by their very nature, their decisions can have repercussions that reverberate beyond just themselves.
