Whenever Hyde committed a crime, Jekyll would defend him. For example, after Hyde stomped the little girl (as related in Chapter 1), Jekyll drafted a check in his name for Hyde to pay off to the little girl's family, but that's not all. Hyde has done awful things, the most heinous of which being the murder case. However, due to a lack of evidence against him, the trial was canceled. Thus, Jekyll paid the plaintiff $10,000 in civil damages and appointed a lawyer to represent Hyde during any future proceedings. Hyde has also done some good in his lifetime. For example, he saved the young boy from certain death. Additionally, he prevented the police from arresting Mrs. Dalloway for suicide. Lastly, he killed a man who was about to shoot Jekyll with an arrow. Although this last action harmed someone else, it did so to protect Jekyll and therefore counts as self-defense. In conclusion, Hyde can play a major role in Jekyll's life by defending him when he is accused of crimes or preventing authorities from putting him in jail. However, if Hyde acts out violently, this could hurt Jekyll greatly. For example, if Hyde murders someone, this would be considered a terrible act and could cause Jekyll to lose respect from others.
