The tall, dark figure is supposed to represent the old executioners from the Spanish Inquisition in Mexico (1571–1820).
The people kneeling around the figure are supposed to represent those being judged or accused, showing fear and submission to the authority of the executioner.
The dark figure standing in front of the group is supposed to represent control and influence, as if they are guiding or commanding the people in front of them.
The followers facing the camera while the figure points the torch are supposed to make the viewer feel involved, as if they are part of the judgment or being accused themselves.
The people laying on the ground are supposed to represent the aftermath of punishment, while the dark figure in the background shows the result of that power and control.
