Ch.10; Jack makes a 'theological speculation' about the murder. Why does the author call it 'theological' and what are the implications of it.

In order for Jack to maintain his rule over the boys he must present the killing of Simon as the will of another force rather than the result of an internal evil that resides in the boys responsible for the murder.

Where Ralph is unable to end his followers’ misery over Simon’s death, Jack is able to relieve his followers’ doubts with theological speculation. Ralph fails with the truth, while Jack covers the truth by shifting the blame to the beast.

The speculation that the cause of Simon's death is due to the beast or some other divine happening rather than the boys places the blame on outside forces. This implies that Jack no longer see's himself as the source of evil.
