Cannibalism

Cannibalism is the practice of eating human flesh. Cannibals appear throughout the Fallout series and Cannibal is the name of a perk in Fallout 3, Fallout: New Vegas, Fallout 4 and Fallout 76.

Background
Cannibalism is considered a social taboo throughout the wastelands, resulting in calls for the "extermination or reform" of anyone who engages in the practice. Herbert Dashwood describes Harmon Jurley as the "psychotic cannibal" leader of Paradise Falls, that was "rumored to eat the slaves he couldn't sell."

Vance, the leader of the Family, explains that cannibals, or those who eat human flesh, are labeled as "monsters, demons and the unclean" by society. He describes his goal of assisting his group in transcending their cannibalistic nature by teaching them to only drink the blood of their prey as an alternative. If the Lone Wanderer still accuses Vance of being a cannibal, he insists that drinking blood is vampirism, not cannibalism.

In the Mojave Wasteland, when the White Glove Society joined the Three Families, they signed a contract with Mr. House which strictly forbade engaging in cannibalism. If the faction violates this agreement, Mr. House states, "Is it really so hard not to engage in cannibalism?" Caesar describes rumors of a cannibal tribe that lived near Vegas in an underground cavern, commenting that this may have been the original members of the White Glove Society. Josh Laurence comments to the Chosen One that he heard tribals eat their own dead, stating that "cannibals is cannibals in my book."
