I will relocate and elaborate on the weakness, many go hand and hand with his personality and history so when I complete those they may make more sense. I welcome any input or advise though, especially if it makes the character more enjoyable for the storyline. I planned on the weaknesses feeding into each other, the alcoholism exacerbating the PTSD, which exacerbates the amoral behavior but I can see how this may not be the kind of weakness you are looking for.

Though I had never planned on playing just the "cool alcoholic" that sips from a flask (planned on making it a real addiction) I could always do a guy in the first or second stage of Cirrhosis. That would be a serious weakness.
