Faustian Bargain In Star Wars

In the introduction, the first pattern Foster points out is the Faustian Bargain—the deal with the devil. Foster describes this bargain as the exchange for "something [the hero] desperately wants—power or knowledge [...] and all he has to give up is his soul" (xxiv). My question is whether this concept can be expanded to include offers for the hero to join the antagonist. The first example that comes to mind is Star Wars. Darth Vader cuts off Luke Skywalker's hand, reveals himself to be Luke's father, and then offers Luke a place by his side that would make both of them unstoppable. Being the noble hero he is, Luke refuses. In Arrow, the Dark Archer, who is revealed to be the protagonist's best friend's father, asks the Hood to join him in the destruction of the Glades. Knowing that the Dark Archer killed his father and the destruction of the Glades would mean killing thousands, the Hood resists. In the alternate Warcraft universe, Durotan, the leader of the Frostwolf Clan, believes his father and brother to be dead after they disappear. When, years later, Durotan and his brother, Ga'nar, find out that the rival Thunderlord clan was responsible, the hotheaded Ga'nar embarks on a crusade to kill the chieftain's three sons.In the final battle than ensues, the Thunderlord chieftain reveals himself to be Fenris, Ga'nar and Durotan's lost brother. He extends an offer for the Frostwolves to join the Thunderlords in the Iron Horde. Declaring his brother a traitor, Ga'nar declines by slaying him. …show more content…
In each case the protagonist has the option of giving up his ideals (akin to selling his soul) for the combined power of the two parties and a stop to further conflict. As a further aside, I wonder how the relation of the two characters changes how the bargain is
