About

His nickname is Andy. He has an interdependent relationship with his younger sister, Ashley. While he dislikes her obsession with him, he finds himself unable to push her away. Compared to Ashley, he appears more human, yet he suffers from a significant lack of empathy. Furthermore, while he is reluctant to commit crimes, he displays a lack of morality no less striking than Ashley's once he actually commits them. If Ashley is closer to pure evil—acting on whatever she finds fun—Andrew is calculated and meticulous. According to the detailed description of Andrew's inner thoughts in 'Decay', he never possessed a proper sense of morality even before the Nina incident. He had simply lived obsessively adhering to two principles due to Renee's coercive and emotionally abusive upbringing: 'I must appear to others as a good person' and 'I must take responsibility for Ashley.' His anxiety after killing Nina or murdering his parents stemmed not from the act of committing a crime, but rather from the intense fear that his mask as a 'good person' and 'good son' was being shattered.
