Having no way to come to terms with his trauma, and being forcibly calmed rather than persuaded during relapses, my neutral character is progressively becoming more evil.

Not gonna lie, that’s true in this universe, too.

I would say that using calm emotions in this context isn’t a quick fix, but it means the traumatized character can be more rational when dealing with what she feels; stuff that was just too much for her before isn’t as much now.
