I mean, we can see that Bo has a level of respect for the MC and is changing as a person if you choose to have Mao take the kids from the orphanage. Hell, even his training in the mist chamber shows that, and he is definitely insecure about his strength when compared to Jack and the MC. Jin and Bo are actually pretty similar in that regard. I do agree that there should have been an option to help him without the soul-binding oath. Outside of the Twins and Kosuke, he is the only one from Thunderfall I wanna see actually do well.
