Nemesis and Greek Mythology

Nemesis was the Greek goddess of vengeance, a deity who doled out rewards for noble acts and punishment for evil ones. The Greeks believed that Nemesis didn't always punish an offender immediately but might wait generations to avenge a crime. In English, nemesis originally referred to someone who brought a just retribution, but nowadays people are more likely to see animosity than justice in the actions of a nemesis.
