Society believes that when something is good or bad it is immutable, which is highly incorrect. Some features that society describes as good can actually be very deceptive. Like appearance, reputation and human nature. Many sources can support this, including: The Strange Case of Dr. Jekyll and Mr. Hyde, "Serial Killers, Evil, and Us," and the interview with Philip Zimbardo titled "Why Do Good People Do Bad Things?" mask a person's true personality. This is what you first notice in a person when you meet him, but you can't always trust it. For an example: serial killers. Ted Bundy was known as “strikingly handsome” (Simone 23), but he was also capable of kidnapping and killing twenty-four women and committing nightmarish necrophiliac acts with their bodies. Society likes to think that if someone seems friendly they are much more likely to be friendly, while people who at first glance seem evil are interpreted as cruel or evil. On NPR, Philip Zimbardo talks about his fake prison and how he carefully selected people classified as normal. He put the guards in charge of what happened in the prison, and they would punish them as they saw fit. Zimbardo said he conducted this experiment because “that line between good and evil, which privileged people like to think of, is fixed and impermeable. With them on the good side and others on the bad side, [he] knew the line was moving and it was porous. "(NPR) This was proven in the experiment; the guards were cruel and humiliated the "prisoners"... some of whom may have been their own classmates. One of the cruelest acts committed by these "guards" was when it was another prisoner's birthday.... in the center of the paper... the breakdowns, one by one. (NPR) The fact that they were normal university kids who had not done anything cruel in the past proves it the kindness and evil that we all have. These boys were not cruel before the experiment, they had simply been pushed across that line of good and evil. The story of Dr. Jekyll and Mr. Hyde, Jekyll was a kind man. Jekyll, Lanyon and Utterson were close childhood friends. Utterson had also said that Jekyll was a good man and thought that Hyde had blackmailed him to get all the money in Jekyll's will had split in two, the good was himself while the villain was Mr. Hyde. In this second state he was capable of trampling a little girl and killing a man all by himself. This whole idea is the very concept that man can actually have good and evil within himself. This split simply allowed Jekyll to get away with everything much easier.
