The image of a distraught Lily was more than enough to snap Ramiel out of his fanatical state. It acted like a solid slap in the face for sobriety.
In a fleeting moment that could have been life or death, he regained his composure and felt a growing terror from the bottom of heart. It wasn't caused by Lily's hopeless predicament. His sister was an even bigger cockroach than he was and would surely last for some time before he came to her rescue.
What frightened Ramiel was the state he was in. For the first time since his defeat of Night Deuce, he had lost his temper... or a better statement was that he was being controlled by something.
Madness and an unbridled desire to spread carnage on a massive scale in the name of what? Chaos? It was definitely not normal.
