I accidentally killed a dog today. I feel really really bad about it.

I feel so bad about myself currently since the incident that happened earlier in the morning. Me and my friend rode our bikes early morning at dawn. Street was quite dark and no other traffic along the way. Me and my friend were doing 90-120kph run and he was behind me.All is well when suddenly a few meters ahead i saw a small dog slowly walking in the middle of the road, looked like he was crossing the other side. The lane of our traffic direction was 3 lanes and 3 lanes on the other side. I was running on the left most part, and the dog was already about to enter the right most lane (slow lane) so i was too confident that he will be able to finish the cross but just to be sure, i moved a lot more to the left most lane almost counterflowing to the oncoming traffic. I didnt slow down nor sped up, i maintained my speed. However, the dog suddenly ran back so fast towards the path of my bike like crossing the middle lane until towards me in the fast lane and I just couldnt stop the bike anymore. There was no other traffic on that particular time, so maybe the dog got spooked by my exhaust pipe and ran back to where he came from. I hit the dog’s head to my feet in the right footpeg and according to my friend, my rear tire run him over after. My right foot felt like it was hit by a rock when it was the dog’s head that hit it.I stopped in the slow lane, and realized what just happened. I was in shock and couldn’t believe what just happened. I didn’t expect it would happen to me running over a beautiful creature like that. I asked my friend to turn back and check if the dog is still alive, then slowly after i followed him. I was hoping the dog would still be alive and we will have time to bring him to the veterinary to you know, save his life. I was running back on the side of the road slowly, still processing what had happened and my friend is already searching for the dog ahead of me. And my friend came back. The dog died. I didn’t have the courage to see the dead dog that I accidentally killed while driving my bike.I feel awful. Very awful. I wish I couldve done things differently. I wish I didn’t run that fast. I wish the dog didn’t cross the street. Maybe he was still alive right now. We still continued the ride but I felt awful the entire ride. I was even crying along the way. I just didn’t like what I have done. I know its an accident but still, I killed a dog. My conscience is eating me up right now and I cannot even sleep when Im supposed to be asleep already.I always tend to slow down when I see creatures beside the street you know, defensive driving. Its just different this time. It looked like the dog is really about to finish his crossing of the street. I was too complacent and the dog paid it by his life. Did you guys experience the same? How did you feel afterwards? I hate this feeling. I feel very sad for the dog. 😭 via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/fd8mka/i_accidentally_killed_a_dog_today_i_feel_really/?utm_source=ifttt
