Intelligence vs. Superiority

One of the most striking scenes for me was the one in which Roy Batty used his chess expertise to ultimately defeat and destroy his creator. This takes place over several scenes, starting with Roy and Sebastian in Sebastian’s residence of uncanny creatures and toys that he has fashioned in his spare time. The contrast between Sebastian’s residence and Tyrell’s should also be noted, as we see the chess board in Sebastian’s home to be rather ugly and oversized, whereas Tyrell’s is clean and elegant. In the midst of this friendly rival between Sebastian and Tyrell is Batty, who sides with Sebastian in order to overcome Tyrell, his creator. Batty uses Sebastian as an excuse to enter his home, but this excuse is derived from Batty’s sheer intelligence, as he is able to defeat his creator in the ultimate mind game. However, as a Replicant, Batty is  inherently inferior in lifespan to Tyrell – Tyrell makes a point of saying that the “candle that burns twice as bright lives half as long, and how brightly you have shown.” Is Batty’s intelligence a sign of how objectively superior the Replicants are to humans, or is it simply a trait that marks the Replicant as not “one of us?”
