English: “Of his free will” — this teaches that he is not atoned for until he is willing.
In the sugya: This is the consent-half that bounds unit 7’s force. Kapparah is not credited while the owner remains unwilling. Compulsion is a means to willingness; without that endpoint, the process is incomplete.
Type of Learning
Condition of consent — kapparah waits on willingness.
What Is Learned
Compulsion continues only until the owner expresses willingness; kapparah requires that consent. Lirtzono is not rhetoric — it is a condition of atonement for this offering.
