Good points about Jake. I'm less persuaded by your arguments about Odo...he may not have felt especially attached to the colonists, but he was certainly aware of their existence and knew what his actions would mean for them. I wonder whether he could have pleaded mental incompetence if he ever went to trial for his actions. While it's probably not fair to take FutureOdo's actions as an indicator of how PresentOdo will turn out, I'm still left feeling that this episode does indicate what he might be capable of, and it's neither the first nor last time we'll see Odo commit morally ambiguous acts. He may believe in justice overall...but he's also willing to make the occasional exception.
