What are the causes for human cannibalism?

Human cannibalism can arise from various causes, including survival situations where individuals resort to eating human flesh to avoid starvation. Cultural practices and rituals in some societies have historically included cannibalism as a form of reverence or as part of traditional rites. Additionally, psychological factors can drive individuals to cannibalism, such as severe mental illness or a desire for power and domination. In rare cases, it may also stem from criminal behavior, as seen in certain violent acts motivated by sadism or other deviant desires.
