BSG 3.07 Salvation

Battlestar Galactica 3.07 A Measure of Salvation (2006-11-10)

With the discovery of a dying Cylon Basestar, Adama and Roslin debate the morality of deploying a biological weapon against the Cylons with the intention of eradicating them.

This could have ended here if not for stupid command decisions. All Adama needed to do was put Helo in the Brig for the duration of the operation. Then there is the implausible plot point of a virus being able to transfer with the consciousness of the Cylons.
