Light Yagami's actions in the anime "Death Note" have a significant impact on his sense of identity and purpose. At the beginning of the series, Light is portrayed as a highly intelligent and morally upright student who desires to rid the world of evil by using the Death Note. However, as he becomes consumed by the power of the Death Note and begins to see himself as a god-like figure, his sense of identity and purpose undergo a drastic transformation.
Light's actions lead him to adopt the persona of "Kira" and believe that he is the savior of humanity, willing to kill anyone who stands in his way. This newfound identity as Kira causes Light to lose touch with his original self, leading him to justify his actions as necessary for the greater good. Over time, Light's sense of purpose becomes solely focused on maintaining his power and achieving his vision of a utopian world under his control.
Ultimately, Light's actions have a detrimental impact on his sense of identity and purpose, as he becomes consumed by his desire for control and loses sight of his initial values and beliefs. The choices he makes throughout the series challenge his core identity and force him to confront the consequences of his actions, leading to a dramatic shift in how he views himself and his role in the world.
