Except that we didn't really see them think deeply about it. One minute Archer was in favour of giving them the cure and then in the next scene he says, "Oh i slept on it and decided you were right and let's not give them the cure" - A little scene showing Archer talking to someone else and/or thinking about his decision changing might have improved the episode more instead of the rapid 180 degree turnaround we got.
I didn't know this, but the ending was originally very different, as stated near the bottom of the Memory Alpha entry
Aside from the controversy here, the episode is excellent as just an exploration of the doctor as a member of the crew. I think his interactions with both Cutler and Hoshi make this episode a winner as well.
I also think the music used during the narration gives this episode a unique feel.
