The Armageddon Lord

I just watched the beginning and don't want to read more, my three views are inconsistent. . . A person who has an army in the end of the world actually doesn't even save a girl, and says he has no value. Isn't this nonsense? Does the protagonist have value? What else is left besides the system? I think it is a normal idea to save people when you can. This pretending to be cold is really ridiculous.

I hope you can help me point out any shortcomings. Rumors in the comment area may not be easily discovered by a person. I will slowly correct it!

I have difficulty naming the disease. I need your help in thinking of some supporting characters. Book friends who want supporting characters can reply in this post. Format: name Ability (with or without, or as an evolver) Type (human or other creature, it can be a zombie or a mutated creature)
