Yeah, and they'll probably keep reaching for ever-greater shock value to replace good storytelling.
I think it's possible to treat these subjects (suffering, trauma, etc.) deftly. We need good art to shine a light on the worst aspects of human nature, just like the best. But it needs to be done well, as part of a good overall story, great characters, good writing, etc. - not as an end in itself.
For a short time a couple years ago, I delved into the subgenre of "disturbing" fiction - fiction dealing with subjects that are allegedly horrible and painful. I say "allegedly" because, although there were a couple of novels that genuinely disturbed me, 95% of them were not disturbing at all. They were not disturbing because they were trying so hard and so obviously to be disturbing. It all felt so artificial, so staged, so heavy-handed, it just fell flat. They lacked the storytelling and characterization chops to immerse you as a reader, so the action just came across as random and meaningless. Not disturbing at all, just a waste of time.
