משך חכמה — שור אחיך / חמור אחיך — לעומת אויבך ושונאך במשפטים

Q — Why does Mishpatim call the animal's owner "אויבך" / "שונאך" while Ki Teitzei calls him "אחיך"?

A — Mishpatim was BEFORE chet ha'egel — when all Israel were "ממלכת כהנים וגוי קדוש" and sin was rare; a sinner was an exception, and seeing one sin generated legitimate hatred. After the egel, sins multiplied — so anyone who sees his fellow sin must search his own deeds and will find his own faults; hatred of the sinner is now reserved only for the truly perfectly righteous ("בני עליה והם מועטים"), and for nearly everyone else the sinner is "אחיך" — an equal in need of love.
