By March of 1945 every adult in Europe with two brain
cells to rub together knew how the war was going to end.
It is clear to me that all who participated in the murder
of these 180 Jews had to have had a history of murderous
behavior that was well known. Joining in on a murder spree
for the first time when your side is losing badly makes
no sense.

They were killing the last witnesses to earlier atrocities.

“Joining in on a murder spree for the first time when your side is losing badly makes no sense.”

I suggest that it never makes sense. True evil seeks no reason.
