I Can’t do the Thieves Guild Questline

the-elder-scrolls-v-skyrim

I'm a Khajiit Character in Skyrim, I just made the character and now I've decided to join the Thieves Guild. The first quest I have to do is collect the debt from the three people, but as a Khajiit whenever I initiate a brawl, I end up doing lethal damage (yes with my fists) and everybody around me starts trying to kill me with daggers and I always end up killing the target with my hands rather than just knocking him on the ground. Any help would be appreciated.

UPDATE: Whenever I'm attacked the target everyone around me attacks as well.

Quick and dirty solution: Change your race:

Open the console (the "`" key next to the "1" key), type

showracemenu

This will show the initial character creation menu. Change your race from Khajit to something else. Complete the quest without scratching your opponent with your cat's claws. Repeat to change your race back.

A sidenote: I had a minor issue with changing race: I've changed from Khaijit to Dwemer, but after each change to werewolf form and back, game was resetting my race to Khajit, forcing me to again manually change it, but since you are in the end want to stay in the original race this shouldn't be an issue.
