The wizards philosophy is that the only really dumb question is an UNasked question. If we don ask questions, how are we to learn?
The wizards used to ask questions back before they knew everything. The WORST torture known is probably being crucified like the ancient Roman Empire did to outlaws, rebels and Jesus Christ. The wizards don’t wish to elaborate in too much detail, but being crucified involves a myriad of slow painful ordeals simultaneously. What the wizards find compelling is that Christ being the Divine Creator in HUMAN FORM selected the most PAINFUL and cruel way to die at the end of his time here on Earth as a mortal. This is example of the Creators ultimate fairness and demonstrates HIS being willing to take on the WORST that mankind can dish out while obeying ALL the rules HE commands us to follow.
