I agree with the profile of the """"gentleman"""" but if you search in the net, you can find catholic organisations defending Gui that """""only"""""ordered the execution of 42 of his 900 victims...
The sources I have seem to confirm that during his life as an Inquisitor, Bernard Gui sentenced 930 people not necessarily to death though).
And if I am not mistaken, didn't Templario already say that Gui wasn't directly involved with the prosecution of the Templars.. (they used a manual he had written...)?
If Bernard Gui had been involved in the trial of the Templars, there would be traces of his name in the proceedings.
By the way, I mentioned that he had written the "Manual of the Inquisitor" and that the procedures described in his book might have been used by the Inquisition during the questioning of the Templars. Although some of the methods may have been used (since he didn't invent all of them), I found that his actual book wasn't used since he finished it in 1323.
