Azekiel still hated himself for running away since he felt that he had abandoned his mother by running away. Unfortunately, even if he stayed behind, he couldn't do anything but to watch her die since the beast was too strong for him, as a human to defeat.
"It's so ironic... The beasts that were like God to me... The beasts that were so strong that I couldn't do anything but run away... The beasts that were strong enough to destroy the entire human civilization! Those beasts are nothing before me now."
"Once, the beasts that made me run away, today they can't even make me flinch. But what use is this strength now?"
He weakly gazed at the lifeless body of his mother, feeling like laughing at his weakness. He was so happy that he was getting stronger, forgetting at what cost this strength came. In his hunger for power, he forgot his last... He forgot that feeling of weakness... He forgot that fear which made him run away in the past.
