I blew through there immediately after the accident. Visibility was down to zero. All I saw was what looked like a deer kill with a mess on the highway and Roadway on the side of the road. It would have happened to anyone. There was no time to react. If fact, I could not have avoided the remains if it had been in my lane.
As for the idiot crossing the highway, there is a Pilot truck stop on the east side a mile up the road that he was likely headed for. At 2:30 in the morning, I would suspect that he was drunk and ran out of gas. He could just as easily have walked north and exited on the on-ramp and then crossed under the highway. That surely would have been safer and would have saved the Roadway driver the grief and vision that will likely haunt him forever.
The pedestrian was an idiot and I only hope that this happened prior to him reproducing. At least then our son's risk of this happening to them will have been reduced.
