She did

You opened your maw of needle like teeth and charged at her. You met in the middle, nearly clashing into each other. In the last moment however, she jumped, and lifted her hammer overhead. When it struck you, the front half of your body exploded, sending scorched flesh and caustic fluids in all directions. The courtyard was a mess. What was left of you reeled back, your other maws screaming in agony. You tried to retaliate, but she didn't give you the opportunity. Another holy blow tore off another portion. All that was left of you was a bloody chunk with an eye, a mouth, and an arm. Your body tried to regenerate itself, but there just wasn't enough time. She stood over you with a grim face.

"M-mommy why..." the voice inside you said, taking over.

Her eye twitched. "My son," she said, more to herself than to you, "is dead! Stop pretending to be my son!" She started to beat you. She beat you with tears in her eyes until you were just pulp. "My son is dead! My son is dead! My son... my son is... is..."

She dropped her bloody hammer, and fell to her knees over your scraps. She let out a sob, tears streaming down her cheeks. You were torn beyond repair. As your being left the mortal plane, you felt bad for her, and you felt dissapointed in yourself for failing your master.
