I'll put a positive spin on it: this bomb killed zero people. Had it exploded, it might have killed people or made them homeless (I'm sure there are war era maps that would help us verify that was there). Most Germans weren't war criminals, and maybe those not impacted by this bomb went on to help others. Maybe they had families or helped other families raise happy children who went on to spread good will.
I'm hopeful we can look at this bomb and believe no harm came to others from it.
