Treyton had already generously shared how others with superpowers could get stronger. If they really didn't train themselves to become stronger, then even if they became food for the zombies, Luciel wouldn't even move to save them or do anything to help.
People always have to learn how to protect themselves, especially in the times they were in. If those who were already blessed with powers didn't even want to improve themselves, then they'd just bear the result on their own.
Well, it's also the same with ordinary people. Luciel would certainly not do anything for people who didn't even want to save themselves.
He, who was already living a good life, still had to work hard to train himself even though he could've just lazed around. So, why should he even bother caring about people who didn't work as hard as someone like himself, who actually wanted to just laze around?
