when you have the dark side, it can lead to greed in what you want because the greed is one of the evil of all human on earth and never disappear because it is in your subconscious. Everyone want to have something, such as money, power and better life or anything. So I can believe that greed, like lust and gluttony.
In addition to this, the most serious thing is that it can lead to the most brutal crimes.
For example, this character is Patrick Redfern. He was a crafty man and exploitation with woman. The quote of him in this story is “He was the type, per excellence, the type of man who exploits woman like her and the type of the killer, the kind of man who will take a woman’s savings and cut her throat into the bargain”.
