The cause of Bob's death

The reason why Bob died, is really because of Dally. He made Cherry and Marcia (Socs)really weirded out because he was hitting on them. Johnny stood up to Dally, and told him to back off. So, they got to sit by the girls. Before they knew it, they were friends. One day the group was walking back from the movie with the two girls, and their boyfriends(one of them was Bob)pulled up and saw Johnny and Ponyboy with them, so they got very angry. Later that night, Bob and 5 other socs and Johnny and Ponyboy were all at the park, and Bob started drowning Ponyboy, so Johnny stabbed Bob. It's like a domino affect that never stops. Dally probably would never think it was his fault, but he should go to jail instead of Johnny. It was just self defense.
