The real purpose of State sponsored torture is to demonstrate to everyone that the State will make mincemeat out of suspects if it will protect the State. Its primary purpose is to create fear and to keep other people from doing what the person who is being tortured did.
The purpose of a private individual torturing another person, such as a person torturing the person who killed a family member, is one of retribution and to inflict as much pain on the killer as possible.
The book of 2 Maccabees chapter 7 contain a great story about torture and how people will resist it if they have the proper motivation. https://www.biblegateway.com/passage/?se...ersion=CEB
In Judges 1:5-7 (CEB) a king used to cut off other kings' thumbs and big toes. One day he lost a battle and was captured. So the enemy paid him back.
"5 There they found Adoni-bezek at Bezek, fought against him, and defeated the Canaanites and Perizzites. 6 Adoni-bezek fled, but they chased after him, captured him, and cut off his thumbs and big toes. 7 He said, “Seventy kings with severed thumbs and big toes used to pick up scraps under my table, so God has paid me back exactly for what I did.” They brought him to Jerusalem, where he died."
According to the Bible God got ticked off and killed everyone in a big flood because they were sinners. People still "sin" so his cure didn't work.
