to express the idea of both fighters willing to do anything to kill each other, which confused some due to Naruto's wish to avoid this fate. The final clash between Sasuke's Chidori and Naruto's Rasengan moves involved references from other scenes of the series to give the viewer a bigger emotional impact.
