Evil

Although I tend to believe J.K. Rowling has no hidden meaning of her story, the characters she put up - Riddle, Slughorn, Malfoy, and Snape - are vivid illustration of why evil people could come along and form a party.

• One of them has a complicated background that end up in a crooked mind and strongly believe he is doing good.
• Some are taken in by the initial charm of the leader or the beauty of Utopia.
  
• Others do not have the freedom to choose.
• A few wished to do something and rectify the wrong-doings.

No, hardly any one would want to do bad things. Even Claudius and Macbeth had their own benevolent agenda. Most of the tragedies in human history came from people who tried to do good in a mistaken way.

And, it is the effort to understand why some people do evil things that put a book to a higher level of achievement.

My salute to Shakespeare.
