I don't think that Zaraki 'hated' the training under Yamamoto, rather I think that he hated anything resembling order and following any direction other than his own. Actually, Old man Yama was like one of the only ones he 'highly' respected because of that awesome reiatsu and ability of his... His respect was shown by actually taking that class with him. It was actually the Old man that stopped training him further seeing his prowess and realizing that if he continued, it could become a problem is he went rogue. I believe that he was allowed to do as he pleased and over time, he become seasoned and calmed down becoming wiser. I truly believe that his was deliberate. Now, really is the perfect time for Kenpachi to activate and train with his real 'true' power...IJS
