How so? The Great Flood drowned everybody except Noah and crew, for one example of OT atrocity.
Atrocity? How about righteous judgement
It is way of all flesh.
Not only do we individually die, but there are total die-offs, mass extinction events. That's our reality on this planet.
I don't think death by flood, one of nature's processes, qualifies as an atrocity. Death just happens. It's equal opportunity. The only thing different about the Flood in Noah's time, is that God saw fit to rescue life on earth.
