unremitting

Were the horrors too extreme, the subject matter too unremittingly grim or simply too uncomfortable to contemplate?

So it doesn’t make sense that a deeper understanding of a complex set of unremittingly cruel brain diseases that decimate the lives of victims, and their loved ones, is no longer a priority.

An unremitting tragedy that permanently altered our lives — where little meaning can be derived and which even less justice has been served.

"In the future, our hope is that machine learning algorithms like ours could help patients' treatment teams respond fast to new or unremitting episodes in order to limit negative impact."

Their answer to this state of affairs will be the steady, unremitting accretion and employment of power — defined predominantly in military terms — to serve narrowly defined national interests.
