Why does alastor always smile

Alastor of "Hazbin Hotel" - what an interesting character, isn't it?Well, as far as first impressions go, his smile is definitely kind of unusual. It's also probably necessary to depict the difference of background enjoyed by his co-stars.---But that is what sets him apart!His perpetual smile is an integral part of his personality. Back in his living days (1920s), he was a radio host, and this happy personality made his radio broadcasts very popular. A radiant and welcoming smile added color to his already mellifluous voice. In this way it helped greatly with even his singing career.Maybe he brought that from human days—after all, it is somewhat comforting, isn't it?To hold onto something human, even after you have left the world of humans!However, perhaps it was because of Alastor's smile that his characteristic appearance came to be. This well-received expression accentuates and completes his accentuates eerie demeanor, seemingly benevolent acts are given a darky spin and telling revenge.It's just kind of... weird, isn't it?Is that not just a bit weird, though, when someone keeps grinning as wide as they possibly can but at the same time is turning things over, one after another, knocking them right and left?Then again, on a deeper level, the ever-present grin of Alastor might be seen as reflecting a desperate light in the pitch dark — an image of gaiety hidden behind grim reality. Perhaps it is aimed more at how things aren't always what they seem: that the most beautiful smiles can sometimes hide something sinister beneath.
