Draconian (adjective) 

Draconian (dray-KOH-nee-un) means harsh or severe. The word refers to Draco, a 7^th century BC Athenian legislator who created an extremely cruel code of law. (Even minor offenses were punishable by death.) As I used it today: “Although I think I understand his reasoning, Seneca’s Draconian requirements for friendship seem unrealistic and contradictory. They are the epitome of selfish benefit.”
