Hello all. I'm writing a fictional book about the end of the world, how humanity sucks, bla bla bla. You get the whole deal. A concept I'll be using in my book is how any ordinary, good person can go bad, and why they do. The reason many people become evil or do this or do that is because they are confronted with a situation that evokes in them a certain pain. When I say pain, I mean emotional pain, negative emotions. I don't mean something vague as "hate" or "sadness". I mean "fear", "empathy", "guilt" and the such. I am looking for the roots of one's pain. Why might someone want revenge? Simple. They lost someone. Why might someone want to fulfill some goal? Simple. They feel guilty. I've looked through such articles like the List of emotions. For certain reasons, I am looking for six different reasons why someone would feel pain. I have found the following: Ego - bad self-esteem / hurt pride / jealousy / etc Fear - self explanatory Loss - maybe death of loved one Guilt - self explanatory Loneliness - self explanatory Empathy - feeling others pain My question to you, is this fullproof? Think of any reason why someone might feel an emotional pain and see if it falls into what I've described.
