Another Trait that has come to mind.

You are Angry. You’ve got a permanent chip on your shoulder — perhaps because the world has been cruel to you, perhaps because you’re just not a nice person. Your anger can drive you through pain and hurt to accomplish things that other people would balk at; it can make make others cower in fear at your rage, or perhaps be swayed by your righteous fury. However, your anger can also drive you to do foolhardy or self-destructive things; it can make others dislike and shun you; it can consume you and others around you.

Very similar to Driven, in a lot of ways, really; but I think the specific emotional flavor of being Angry makes it a worthwhile addition all by itself.

I think this one should require specifying what you’re angry at, though I think something extremely broad (like “Angry: At the Whole World”) could conceivably work.

Might be difficult to make work in a group of PCs, but perhaps in a one-on-one game? Or perhaps if combined with other Traits, such as making the anger a secret, or also being Happy. Perhaps.

As always, let me know how this Trait works in your games!
