After the initial collision, the psyche protects itself by flattening. Numbness becomes a survival tool: you stop reacting the way a “normal” person would, because normal reactions would destroy you.
This apathy is not indifference in the ordinary sense. It is a defensive narrowing—less feeling, fewer thoughts, a focus on the next task, the next ration, the next hour.
The danger is moral erosion. When suffering is constant, compassion can feel expensive, and cruelty can become ordinary.
Yet even inside apathy, a thin line remains: you can still decide whether to become purely self-preserving—or to keep a minimal allegiance to decency.
