Was Mordechai mekayem the mitzvah aseh of מְכַשֵּׁפָה לֹא תְחַיֶּה based off the understanding of the Ramban here that it is a mitzvah Aseh to kill a sorcerer.

Using the understanding that Haman was a grand sorcerer (See Here and Here.)

looking from the Kedushas levi Here it seems that Mordechai hanged Haman himself.

would this mean that Mordechai was mekayem MItzvah Aseh D'oraysa of killing a sorcerer?

additionally, from this it can seem that there are times that a conviction by beis din is not necessary.

(I wonder how many individuals throughout Jewish history have been mekayam this mitzvah...)

    Shimon Ben Shetach did sefaria.org/Rashi_on_Sanhedrin.45b.22.1?lang=he it might be that the mitzvah is on jews not non jews though.

  • There is an argument whether a non Jew is forbidden to do Kishuf in Sanhedrin 59b - the Rambam does not mention it among their prohibitions

  • I think the mitzvah is to do so based on a psak by beis din, so probably not. The mitzvah he did was protecting the Jews.

    Of course, like almost anything else. Not necessarily brought in, but you would need valid testimony and a psak from the Beis Din.
