Why the prisoners quickly lose their instincts of self preservation self defense and pride?

Prisoners often quickly lose their instincts of self-preservation, self-defense, and pride due to the extreme dehumanization and trauma they experience within the prison environment. The harsh conditions, constant surveillance, and violence can strip away individuality and autonomy, leading to a survival mentality that prioritizes conformity over personal dignity. Additionally, the psychological impact of isolation and hopelessness can cause individuals to internalize their circumstances, diminishing their will to resist or assert their identity. As a result, many may succumb to a sense of powerlessness, which undermines their natural instincts for self-preservation and pride.
