For this question to be valid, this would mean that the rush one gets from racing, the high one gets from drugs, and the pleasure one feels after hitting someone they hate are all not only good but okay things to do. There are many temptations in the world, and many of them are very harmful. Malachi Constant is a textbook example of this.

"Magnum Opus is no more. [Fern] and [Constant] are the last two people in the building. Everyone else has been paid off and sent home," (p. 68). Work...
