If you chose to let the Injured Minotaur live, you were told to get him 5 rounds of Salve.
Run to Harf Trading Post, buy 5 Salves at the Auction House, and run back to the Injured Minotaur.
After this, you recieve a quest called Injured Friend, where you're just supposed to walk back to Evon
at Khalara Watchtower, and tell him the Injured Minotaur is allright.
