The right of the pursuer to oppose neutralization

This issue appears in Zimri. The Gemara says that if he had turned around and killed Pinchas from the pursuit, he would have been exempt. In Malam Pa’a Mahal’ Rottsach discusses the expansions of this law (what about an accidental murderer who kills the blood avenger, and there is still a discussion about who kills the messenger of the 14th century). The pursuer has no right to oppose neutralization, just as he has no right to kill. In fact, he himself was obliged to kill himself by the law of the pursuer (or, of course, to stop pursuing). This is how I explained here a few weeks ago the law that a messenger in a court of law is not permitted to kill him because the accused himself must kill himself. Killing criminals is a commandment imposed on the public, and a messenger in a court of law is a messenger for everyone (including the persecuted).
