Cannibalism!!
Cannibalism is the practice of eating the flesh of your own kind.
People eat other people because maybe something in people snap, or they have twisted mines, or it could possibly from a bad childhood. Some people need to do it, it all depends on life or a death situation. You could be starving out in the dessert or something and you have no choice but to eat other people. Some other things why people do this is because they could be ill and craving it and they are just sick, or it could be just a culture thing.
There are 3 different types of cannibalism, there is Survival, Endocannibalism, and Exocannibalism. Survival is where you eat human flesh in emergency situations, Endocannibalism is were you eat human flesh from a member of ones own social group, and Excannibalism is were you eat human flesh outside ones social group!!
