You have a point, but remember that Gin murdered the third seat of squad 5, just to be able to join Aizen and he helped Aizen perform hollowfication experiments which resulted in the deaths of many Souls/Shinigami; meaning Gin was no better than Aizen from a moral standpoint.

So the real reason behind Gin's attempt to kill Aizen appear to be the assault on Rangiku many years earlier, a crime to be sure but hardly one to warrant Aizen's death.
