Alfred had lost his mind. Even if he hadn't completely gone insane, he was very close to it. The revelation of Waldo's true power had dealt him an unimaginable blow. The thought that Waldo might have achieved perfect transformation into an undying body had shattered his pride and confidence in an instant. It felt as if something within him had collapsed entirely at that moment, leaving him dispirited and utterly cold.
Seeing Alfred's state, Waldo knew that he was finished. Alfred had lost his will to fight and was as good as dead. To Waldo, Alfred no longer posed any threat.
However, even if Alfred had retained a strong and unbreakable will, it wouldn't have mattered. His strength had been thoroughly crushed by Waldo. His body and internal organs had been brutally damaged. Now, Alfred was nothing but a broken man. No matter how strong his fighting spirit, he couldn't exert any of his powers.
