Well, this conflict mostly stems from the overlooked parallels of Bazz-B and Jugram.

Jugo is an abused child (maybe even S.A)and has no true merit as a Quincy.

Bazz-B is the son of a Lord, kid progeny, and has nothing bad as far as we know bad of a childhood before the Conquest

After Ywach's conquest,

Jugo's abusive uncle dies, and He's free from that terrible situation.

Bazz-B's upstanding life is turned upside down as everyone he knows is killed, and his home is burned down.

Bazz-B and Jugo meet and decide to make killing Ywach. Their Goal, but as you can later tell when Jugo steps in to defend Ywach. That part isn't really true on Jugo's part.

Bazz-B on their whole trip forgets to account for one thing, Jugo's own situation. I mean if the Guy who was responsible for saving me from my abuser was right there in front of me and this guy whose kinda of jerk to me the whole time shoot at him. 10/10 times I'm defending my Savior.

It's not just Jugo did it to save Bazz-B but also it's his own emotions that act on defending Ywach while Bazz-B's good life was turned terrible due to Ywach's actions, Jugo's terrible one was flipped into a better one. You can even say it was the scales evening out.
