The Wolf was a loyal Shinobi but perhaps too loyal to the Iron Code that caused him to follow the absolute order of his parent which was to tear apart everyone that stands in their way and abandon his master the Divine Heir. The massacre resulted in Wolf's mind being engulfed by the shadow of Shura after realizing the death of those whom he killed in his Vicious Struggle were in vain as he had to forsaken the reason he killed them in the first place. This resulted in the death of Owl himself and Wolf acquiring the Open Gate with which he brought doom upon Ashina.
