i think that there were 2 different flashbacks one with aizen and the other random shinigami holding a hogyoku-like object propably made from aizens experiments and the other one is maybe some time later with the random shinigami who did "naughty stuff" to rangiku and gin watching them.So i think the reason that gin wanted to kill aizen was chivalry(?) because he didnt like what aizen's subordinates did to rangiku, pretty lame but unexpected nonetheless.
