The case mainly profiled in the article above occurred very near my work. It was very big news here for a long time, and people were angry. Very angry. The interesting thing is that they weren't angry at the father who so tragically forgot his son was in his car.
Instead...
They were angry at themselves for thinking it could never happen to them, for thinking that they were "above" every making a such a mistake, and for judging another. They were angry that it happened, and that a child, a family, and a community suffered so. They were angry that a family was so tragically torn apart, and that the father was feeling so overwhelming guilty for what was an honest accident/mistake (there is no word to capture what it was). They were angry that the country from which the child was adopted considered halting adoptions as a sort of "punishment" for the accident/mistake.
They were angry. Just angry. And sad. Overwhelmingly sad. Hopelessly sad. Nothing would bring that baby back, and prosecuting (and persecuting) the father for something he did with no malice, and no intentional negligence, would not fix anything.
It is easy to say, "It will never happen to me," but it is far harder to admit, "It could have been me." It is easy to judge others, but it is far harder to forgive them.
