For myself: torture or interrogation, hooded while moved. Same if I was the torturer. Increases fear, makes the victim wonder what is happening and where they are being taken. Then when they are secured, jerk the hood off and let them abruptly find themselves in the torture chamber. Torture /interrogation is a private intimate activity at least for fantasy purposes.
For execution, no hood, if in public, hood if in private. Public executions are partly to shame the offender and set an example. In a private execution, what's the point.
Of course the alternative to both is no hood, let the miscreant see exactly what's coming to them.
