Morale is the emotional power of a team or an army.
Morality is a standard of behaviour believed to be right by a religion or a religious organisation.
A body of religious people is called a church.
A church decides on the morality of its congregation.
Armies are driven by their devotion to a cause.
Religious belief has been the driving force of armies for many centuries.
Armies fight with the religious conviction of their nation or society.
All armies defend their right to the freedom of their own beliefs.
Religious conviction to their moral beliefs dictates the morale of an army.
The more a person is convicted in their belief that they are morally right, the greater their emotional need to defend that right and that belief.
Being wrong is never good for morale.
