As a character, Egg isn’t apathetic. I feel as though his nonchalance is being misconstrued as a lack of personality or passion, but I disagree.
Egg cares deeply about the server and the world around him. He keeps his own records of his and Wemmbu’s adventures, enjoys reading other historical records of the server, and approaches every new story with a whimsical curiosity. I don’t understand the urge to flatten that out to make him apathetic.
And in terms of his morals being “inconsistent” (I do not think Egg’s actions often conflict with his moral compass and values) I think there is something to be said there. But, it still isn’t apathy, Egg simply lacks conviction. Having no back bone ≠ being apathetic. There is more to support the view that Egg has very solid thoughts, beliefs, and opinions, ones that in private he often states, but in person rarely defends, than there is supporting the idea of his apathy.
Honestly, I do not think Egg believes he can defend his stance and values on the server. He is not a fighter, he is not a politician, nor is he a strategist, Eggchan is a bystander. A bystander, that like many people in real life, cares for the cause as far as their comfort and perception of their own power allows them. That doesn’t mean he doesn’t care, the tragedy is that he does and doesn’t know what to do about it.
