It is devastating how much of the princezams self esteem/self image is based on how much those he cares about cares about him. After every betrayal no matter how big or small we see him spiraling and spending so long with wallowing in that hurt and wondering what we did wrong, or what he could have done to prevent it.
And whats fascinating the most to me, is that this pacifism arc was basically a solo arc for zam, where he should have had a chance to gain his own self confidence in his ideals and ability. BUT it somehow seems to have had the opposite effect ! Where, he now clings even more tightly to the few people who he can rely on( his whole having "only four people that care about him" on the server). And despite people telling him that those four people are enough(Derap), he doesnt believe people, he cant trust them fully ever, and so the cycle repeats. He constantly doubting his own fighting abilities, his own morals, his own everything !! He never believed he could stand alone and in a self fulfilling prophesy he fails !!
