Light Yagami's upbringing plays a significant role in shaping his worldview and motivations. Growing up, he was raised in a loving and supportive family environment with high expectations placed on him due to his intelligence and capabilities. This upbringing instilled in him a strong sense of justice and a desire to make the world a better place. However, as he matured, he developed a more cynical view of society and became disillusioned with the lack of consequences for criminals.
This, coupled with the pressure to live up to his family's high standards, ultimately led Light to adopt a more extreme and morally questionable approach in his quest to rid the world of evil. His upbringing, while initially nurturing his sense of justice, also contributed to his rigid and uncompromising moral code, driving him to extreme measures in pursuit of his vision of a perfect world.
