We are all connected. When one arm or foot is poisoned, the whole body becomes infected.

Kassem frames human society as a single organism: harm to any member ultimately harms the whole. The image of a poisoned limb spreading infection suggests that injustice, cruelty, or neglect cannot be safely isolated—social ills metastasize through communities via fear, retaliation, economic disruption, or moral corrosion. The line also implies an ethical imperative: solidarity and care are not merely altruistic but necessary for collective health. Read this way, the quote argues against indifference and scapegoating, urging readers to treat others’ suffering as a shared emergency rather than someone else’s problem.
