Unlike the previous vague threat to the life of the Angels of Supremacy from before, Zatiel was now declaring that they will need to kill Dimitry if they want to work with him.
Nero's reaction, however, was not anywhere near as aggressive as when the Neo-Demon threatened Sebastian and the other two.
The seven winged Fallen looked at the unconscious Angel of Supremacy in the ground. At first sight, you could not detect anything on his face but if you look carefully enough, you could see the disgust in his eyes.
He was not a hero who travels through the world trying to destroy evil, but he could not stand acts of senseless cruelty happening in front of him. Especially when they are done just to obtain pleasure.
Even if he had not been born with a mutated bloodline, he would have still become a Fallen, since he could not accept the type of mentality of the Heavenly race. But the type of Fallen like Dimitry was even worse in his eyes.
