Final answer:
Sanchez is enraged posthumously due to a combination of unresolved feelings, regrettable unpredicted events, and a keen sense of his own mortality and missed opportunities for personal growth. His complex emotions stem from the realizations that surface upon reflecting on his life and the relationships he left behind.
Step-by-step explanation:
The question seems to revolve around the complex emotions experienced by someone upon learning about Sanchez's death six months after his passing. The feelings of anger are fueled by unexpressed affections, unacknowledged grievances, and the realization of one's own mortality and smallness. The sadness and anger may come from missed opportunities for reconciliation or the unfulfilled intentions of the deceased, as Sanchez had plans to visit his mother that never materialized.
In reflecting on the reasons for Sanchez's posthumous rage, we can surmise from the texts provided that he experienced a range of emotions during the limited time after his diagnosis. Feeling angry, sad, and scared, he also expressed gratitude for having the chance to live authentically as himself, even if only for a short time. This mix of gratitude and unresolved feelings towards others, including his mother, could contribute to the turmoil and rage someone might feel after his death.
From a broader perspective, this inquiry explores the themes of regret, authenticity, and the human experience of processing unresolved emotions in the face of death. It touches upon how unexamined opinions and feelings can persist after someone's death, creating a sense of limitation in life and beyond.
