Yeah, Swanson is pretty miserable, but he isn’t really important for the story, so you can ignore him most of the time. Sadie on the other hand. You are forced to deal with her all the time. Even if you don’t like her, you are forced to deal with her annoying bullshit all the time because she takes part in almost every story mission.
Yeah he was an alcoholic and drug abuser until Chapter 6 where he goes clean, starts thinking more clearly, and runs away and becomes a straightened out priest in New York. He is annoying in the first few chapters but he becomes good later. I hate Molly though
