Why 'Active Disruption' Is a Distinct Category of Harm, Not Just Another Bad Event

A philosophical and scientific argument proposes that not all harm is the same, identifying a specific category called 'active disruption' — harm that works by dismantling a victim's capacity to sustain itself. Unlike passive neglect, competition, or random misfortune, this type involves an agent who directly benefits as the victim weakens, mirroring the biological concept of parasitic virulence. Two independent research traditions — moral psychology and parasite ecology — arrived at the same structural distinction without cross-referencing each other. Psychologist Roy Baumeister's work on cruelty further aligns with this framework, describing harm rooted in gain or ideology rather than abstract evil. The author argues this category is empirically testable and should be treated as mechanically distinct, cutting across the traditional doing-versus-omission divide in ethics.
