Gin knew how dangerous Aizen was since the first time he saw him, he probably wouldn't give a damn whether he was imprisoned, exiled or executed as long as he could kill him.

He was persistent, though, he pursued his goal for 110 years, maybe a bit more, and made himself a criminal, all for the sake of killing the most dangerous Shinigami in existence. And all of that just to make up for whatever damage it's implied that Aizen or most likely his hencemen did to Rangiku.

Although he committed crimes on his way, he kinda earned my respect for going through all of that for 110 years only to stand up against Aizen and kill him, which he would have succeeded with if it wasn't for the Hôgyoku.
