Describe how dally seems to change from the begining of the story until it ends

Dally's real name is Dallas Winston, and he is the toughest member of the greaser gang. Ponyboy describes him as having "an elfish face, with high cheekbones and a pointed chin, small, sharp animal teeth, and ears like a lynx. His hair was almost white it was so blond, and he didn't like haircuts, or hair oil either, so it fell over his forehead in wisps and kicked out in the back in tufts and curled behind his ears and along the nape of his neck. His eyes were blue, blazing ice, cold with a hatred of the whole world."

He is a jockey, and surprisingly doesn't fix races; it's "the only thing Dally did honestly." Although he is only seventeen years old, "the fight for self-preservation had hardened him beyond caring." When Johnny dies, Dally cannot handle his world. He no longer wants to cope. He loses hope and lashes out at society one final time.
