Accidents due to forces of nature are one thing, but accidents caused by the utter stupidity of a person really are difficult to reconcile. I think of it as a pivotal moment when so-and-so was born, or took employment somewhere, and events are set in motion that are going to wreck the life of another person and seal their fate. We live our lives totally unaware that we may be on a collision course with someone who is going to ruin it for us.
