Disloyal is a good name as well. (Rebel isn't, as it implies Renegade, which wouldn't always be the case.) The personality itself, however, is fine.
It's the other personalities which aren't. Savescumming in order to get the ideal trait bonuses is a huge drain of time and degrades from the play experience. From a game design perspective, the choice is a simple dichotomy: to help the players automate that specific task, or continue to encourage savescumming. The correct answer is to help automate it, which is why it's important that the various personalities give a collection of viable trait bonuses which fit to common character archetypes. I feel the six most common would be pure Dex, pure Str, pure Int, Str/Dex hybrid, Str/Int hybrid, Dex/Int hybrid. From there, it's not rocket science attaching certain traits to certain automated personalities; for example, all the Str-based ones would be Vindictive, all the non-Str ones would be Forgiving.
