I don't know about places to read more about it, but if you want to be psychologically damaged yourself without even being a participant there is a lot of drone footage from the Ukraine war floating around on the internet.

These clips highlight lots of incredibly disturbing events like Russian soldiers having exploding drones blow up close enough to them to cause eventually-fatal injuries without actually killing them, forcing them to kill themselves (and in some cases, their friends) with their own guns.

Its horrific to see on a human level regardless of the political circumstances of the war and who is or isn't in the right.
