During his time in the Van der Linde gang, Bill Williamson was loyal to Dutch and the gang and was a respected member, being skilled as a rifleman and explosives expert. Because Dutch gave him purpose, Bill is loyal to him to a fault, and staunchly supports Dutch's every decision, even after Dutch starts going insane. Bill's loyalty to Dutch is implied to be at least partially motivated by fear; not of Dutch himself, but of what the future holds for him should he end up alone again.
