I remember reading a few different Edgar Allen Poe short stories that really stuck with me. I think it was The Cask of Amontillado or something like that where the main character gets his enemy drunk and lures him to a horrible death. For some reason i read that one more than any of his others, it was just so creepy and confusing for a young teen, I couldn't understand hating someone so much that you'd go through all that trouble to torture your enemy. Still can't understand that intensity of hatred but i know it exists in the world.
