Haha yeeeeeah >> although my Atem may or may not have one as head canon (on that topic...) it's nothing that extensive... the artist that drew that one has some extensive ridiculous judeo christian au going on
This is somewhat canon such as the way he adheres to his own brand of justice but I also extend this to other things like an incredibly profound faith in the gods.
And like I wouldn't call him inflexible because he's shown as being adaptable in a lot of situation but he still holds really strong beliefs about the ways things should be
Rather I hope it's specific enough because that's kind of a blanket statement you can make about a lot of main characters and it's hard to convey the particularities I headcanon about Atem
