Nefesh - Animal Soul

"Even a man who is pure in heart and says his prayers by night, may become a wolf when the wolfbane blooms and the autumn moon is bright."

The Wolf Man, Universal Pictures 1941

Zohar Vol. 12 Tetzaveh Section 6. verse 55.:

If that man does not guard it but uproots this supernal Holiness BY BECOMING ANGRY... It is forbidden to come near him or join him. Such a one "tears himself in his anger" (Iyov 18:4). He tears and uproots his soul because of his anger and causes a foreign El to dwell within him. In reference to him, it is written: "Cease from man, though his breath be in his nostrils" (Yeshayah 2:22), meaning that he tears his holy Neshamah and defiles it in his anger, MEANING BECAUSE HE BECAME ANGRY, exchanging his Neshamah in his anger. ...

Zohar vol 10 Yitro Section 12. verse 192.:

This is a man of anger.... His forehead is creased at the time of his anger, similar to a dog ...

But Israel (Ba'al Shem Tov) was just as determined to destroy the werewolf. And with the holy words, " Hear, O Israel, the Lord is our God, the Lord is One," on his lips he struck the animal mightily on the forehead with the stick.
