Will the solarium GOOD ending ever be cleared?

L'appel du vide literally means "The call of the void" in a context where you are at the verge of a cliff and you get intrusive thoughs about jumping, not void as in The Void.
It's about auto-destructive behavior, not about destroying other things (Unless destroying specific other things would indirectly cause you harm, like for instance a sudden intrusive though about how easy it would be slam someone's head with a hammer, you'd basically destroy your life by doing so.)

Maybe walk into the HEPT wearing just the shield of souls and the armor?
