Thanks for the help! :)
EDIT: Thanks for the info so far everyone! But I think that I should delve into more how the person I want to become a cannibal becomes one in the story. The cannibal character in question at a younger age witnesses his mother killing his father once she discovers that he cheated on her. The mother throws the father's body in the basement. Well, the son is about to run out of the house and pretty much rat on his mother, but she gets to him first. Now she has gone over the edge and is saying things like "How DARE you try to turn your back on me like your father did!" so she throws him into the basement and locks him in there... with his dead father's body. Now this is a very dark and crazy idea... but could someone be driven to insanity by this... and if not fed or given any food for the longest time... and being locked with his dead father's body... and end up, in an odd turn of events... eat his own father's body? And from that moment on be horrifically become cannibalistic?
EDIT 2- ACID FOR CANNIBALS: Again, thanks for the help! If you scroll down and see a large follow-up to a post, you will see that I have a couple more questions and some conclusions to this topic. But a new question I want to ask now is the involvement of acid. Would a cannibal use acid to tear down body parts for easier consumption? Or in a more twisted fate, if the mother was feeding her son people, could she make them consume acid to make them be instantly killed and at the same time be more suitable for eating? And how is acid stored anyway? lol. Special kind of jars?
