The fault for much of this foobar ultimately falls on light and dark boy's shoulders. These two each think they know what's best and have WAY too much power to back their feuds. OF COURSE Salem would spit in their faces after that. What else was she supposed to do, find another meaning in life with no guidance regarding how?
It's a pattern that's likely going to keep coming up in this show. Those in power deciding they know what's best and ignoring the needs of those they "shepard" or "guild." Thus far, it's only ended in tragedy when they attempt to enforce those ideals. We've seen it with Ospin's creation of the academies, resulting in Pyra's death and Hazel's bitterness. We've seen it with Wiss's father and his dysfunctional family. Now we've seen it with Salem and the two god brothers as well.
I'm really kinda hoping this show ends with the gods understanding they can never have exactly what they want and leaving permanently. Centering power on a mass scale like that isn't doing much good for anyone. Initially it appears there are only two extremes this can end in. However...
As stated in Volume 4, "If you take a second look, then maybe you find there's a way around as well." Ruby's eyes might hold an aspect of that resolution if she can lay them on Salem and restore some of her empathy. I've posted about that theory elsewhere.
