Loyalty vs Honesty

In R.A. Salvatore's DemonWars Trilogy, some of the largest problems come from blind loyalty to a leader that has gone astray. In the story, the Abellican Church is lead by a father abbot who throughout the story makes questionable decisions that seem to go against the ways of the church. Many of the monks of the Abellican Church follow the father abbot blindly by saying that God choose him to speak for Him so he must be making the right decisions. However, many of the heroes of this book follow true to their heart, a kind of self-honesty, that makes the very distinct enemies of the Church. Ironically, those that are staying true to heart are more in line with the very morals of the the church and should be the ones praised by the church, not hunted and executed. The question is, Is there ever a correct time for blind loyalty or should everyone always follow what their heart tells them to? It seems like an easy question but should soldiers question loyalty? It very may be that a commander has much more experience in combat and his subordinates should follow blindly. It is amusing that this was the first example that came to mind because Salvatore uses that same example within the book. A group of soldiers are asked to arrest a group of "criminals" and while their leader is a exemplary example of a loyal vassal, he breaks that loyalty because he feels as though the wrong decision was made about the "criminals". Personally, I don't think there is a right or wrong answer to this question. It may be that every situation provides a different answer.
