I don't think anyone left an injured person behind. Sounds like he was tired and they decided to complete the last ~1 mile at different paces. I've done it several times when hiking with another person, sometimes while leading and sometimes while trailing. Probably not the 100% safest decision, but also not that bad. I'm not going to cast any judgment on his hiking buddy or their mutual decision in this tragic incident.
