Final answer:
It is unclear why Zach blames himself for what happened to May without additional context from the story. Zach's sense of guilt or responsibility could relate to events in the narrative we are not privy to.
Step-by-step explanation:
The provided text appears to come from a piece of literature, which deals with characters and possibly themes of guilt, responsibility, or self-blame. Without additional context, it is challenging to determine precisely why Zach blames himself for what happened to May.
In literary analysis, context is crucial. The fragment suggests that Zach may feel a sense of guilt or responsibility for a situation involving May, despite another character, Marcus, implying that it is not Zach's fault. This internal conflict and the tension between personal feelings and external opinions is a common theme in literature. Characters like Zach often grapple with guilt and blame as part of their development within a story.
Without further text or reference to the story's events, we can only speculate about the detailed circumstances leading to this emotional turmoil. Typically, this self-blame could stem from incidents where characters feel they have caused harm, failed to prevent something, or made a decision that had unintended negative consequences.
