I killed a lady because I couldn’t stop in time

I (35m) was driving home from work one day, I work in a big city and commute to a smaller city 30-40min away. I was going about 40-50mph and was about 1/2 mile from the hospital where I work. Just before the intersection for the hospital there is a red light and a cross walk for pedestrians. As I was approaching the intersection, a red car stopped on the side of the road, an elderly lady jumped out of the car and saw the crosswalk light was red for pedestrians. She argued with a few people, tried to cross the road despite the red light and got hit by me. I was going about 50mph when I hit her and she died at the scene seconds later. The police came and took my statement. They took pictures of my car for proof I wasn’t lying and released me from the scene. <br><br>I’ve been driving for a tiny bit too long and I just screwed up. I can’t stop thinking about it. <br><br>I called my OBGYN and he said it would be best to tell my wife. He said I wouldn’t need a miscarriage if the mom is stressed and not thinking about the kid.<br><br>I told my wife and she looked at me and said “you’re a fucking idiot”. I surprised and said I know. She then elaborated that I should be careful but she understands I’m not a killer.<br><br>I just really needed to talk to someone about this before I lose it someday.<br><br>Edit: I’m only 35, I’m not old.<br><br>Edit2: I was a medical student whens it happened. I wasn’t a resident or doctor at the time. <br><br>Edit3: I was about 30 feet away and had a green light to cross. I’m really not sure what else I could have done, I was paying attention. The woman literally was talking to people about not being able to cross and then just jaywalked.<br><br>Edit4: I was not speeding. The speed limit was 50, I was doing about 45-50. We have a ton of speeding tickets from that intersection. <br><br>Edit5: My wife was pregnant at the time. I’m now a dad of a 3 month old baby boy.<br><br>Edit6: I’ve lost count of all the comments. I can’t make a full list of responses. I’m just going to stop here and let people think what they want. I’m not mad at the people who say I’m the asshole. I understand it’s a fucked up situation. I’m just glad a lot of people think I’m not an asshole.
