One more thing: guilt ... you would need bad intentions to feel the full measure.
Bears repeating!
5hit happens and sometimes it sucks...bad!
Every dog I have had and will have will ride in the car with me. If a creature runs out in front of the car, I will reflexively hit my brakes/swerve/whatever. I will adjust the radio, answer a call, etc while I am driving, so I won't always see a hazard as early as is possible. None of these things make me a bad person. Knowing your unfortunate circumstance is not going to lead me to change any of those behaviors anymore than knowing my daughter is at risk would cause me to prevent her from driving.
Life has risks and sometimes you are that unfortunate fraction of a percent.
PS - I lied when I said "If a creature runs out in front of the car, I will reflexively hit my brakes/swerve/whatever." If it is a squirrel, I will not attempt to avoid them. We have lots around here so it is a common situation. I got very frustrated attempting to avoid them; if I zigged, they zigged, if I zagged, they zagged; I could not dodge them. I guess my thought process is too close to a squirrel's! Now, I leave it to them to avoid me and their survival rate is much higher...but that is exclusively squirrels!
