That's an excellent point too. Loyalty yo an individual can only go so far. On the other hand, loyalty to an ideal, belief, or ideology, tends to run much deeper. Hence Ashley and Kaidan reacting as they do. If push comes to shove, many (or at least some) of the Cerberus crew of the Normandy would likely evaluate their loyalty to Shepard (inspired by a singular act of heroism) and their loyalty to Cerberus (inspired by shared ideologies and beliefs), and find the Commander wanting.
