Greed is one of the Seven Deadly Sins, meaning that it can lead a person to do other things immoral or act as a motivator for evil. Also known as "covetousness", "avarice", or simply as "greed"; all describe an excessive desire to possess something. A person may commit greed through coveting other's possessions or qualities, or by willing to do something evil to get power, money, physical possessions, or knowledge. The demon that represents greed is Mammon and the corresponding virtues for greed are generosity and detachment. Greed is condemned in the Tenth Commandment.
