Basically. As I have grown up, it really does dawn on you how absolute shit having nothing to contrast bleakness just becomes fucking pointless and stupid.
To only focus on negativity because destroys your creative outlook and makes you like Anno where the man suffered breakdowns due to it.
There's a reason why I have seen people say Attack on Titan died the second they removed the Titans and tried to go Grey and Grey because there's no way in fuck you can make a conflict like that make sense without ultimately just making the entire story shit(which is what happened).
You need to have actual contrast to the darker issues or otherwise, no one is going to fucking care about your story(Again Attack on Titan, I have seen plenty of people refuse to watch series like this because when you just continuously kill characters for shock value, why get attached to ANY of them?)
