I believe he was a pretty "eye for an eye" guy: "This is the right of retaliation (jus [lex] talionis); and, properly understood, it is the only principle which in regulating a public court (as opposed to individuals’ private judgement), can definitely assign both the quality and the quantity of a just penalty."

There is significant axiomatic and theoretical foundation that brings Kant to this conclusion, which has significant influence in modern ethics.
