Honestly if it was truly an accident then eventually i could probably forgive the person.

I wouldn't have to forgive someone that didn't make it out alive from running over my child in the street. That person would be dead by definition, from your question.

It would be an almost impossible thing. But I have seen this from the other side, and that would be in my mind as I dealt with it. When I was five and six, I stayed before and after school with a babysitter. They were very good to me and treated me like their own child. I loved them and I loved their kids. The father of the family drove a delivery truck for a small butcher, which was still common then. You didn't have to go to the supermarket often. The butcher came around once a week and put the meat right in your fridge. The dairyman came around every couple of mornings. The egg lady came around once a week or so. Anyway, this man loved children, and he used to carry a box of penny candy on the truck, which he would give to the kids at every stop. One day he thought he given candy to all the little kids at the stop. He put the candy away, checked his mirrors and started to back out of the driveway where he'd parked. What he didn't know was that a little two-year-old boy had left his house without his mother knowing and was running to get his candy. The boy was in the blind spot behind the truck. He backed over him and crushed him under the wheels. I can remember this as vividly as if it had happened yesterday, not forty years ago. I can remember him day after day, walking into the house and leaning against the wall, wrapping his arms around his face and sobbing like his heart would not just break but burst. It scared me, because I was so little and I didn't understand. His grief was so searing that I thought he would not survive it. We moved soon after, and I've only seen him once in the years since. I've often wondered if he was able to wall it off enough to function, as he had two small children of his own to raise. Just telling the story has tears in my eyes.

I could forgive; that doesn't mean I could forget.
