In A False Glimmer, the season finale of Homeland's Season 5:
Saul has Allison killed.
Putting aside the trope'ish nature of this execution (the CIA would never do this in real life), why is this course of action chosen?
Wouldn't it have been better to catch Allison, with the amount of evidence now against her, and have her instead locked up in prison for the rest of her life?
I would have thought that this would be a much more satisfying option for Saul, given the person would have to then deal with the consequences of their actions rather than taking the easy way out.
I saw the episode awhile ago, but this has been bothering me ever since!
