((At this point? I could care less. It's difficult to oppose someone doing something specifically if you oppose them, because it's like stepping on a trip wire farther down one side. It still causes the trap to go off.))
While I could continue to argue about your idea of everyone being puppets and the hypocrisy of you being insulted by things yet feeling free to do the same to quite literally everyone else, we both know what the other would say, and we both know what the other one thinks about it.
So let's move on to the part where I, for once, agree with you. Regardless of whether the Void has Good applications, such a massive summoning ceremony is certainly neither Good nor safe for either God or mortal. A concentration of Good such as that...Well, I suppose now is a good a time as any.
Create the Arkanjel Viminal, the Angel of Confession. Purification powers, particularly of magical influences, whether they be Void, Divine, Mortal, or Other, and of Evil, mind-reading abilities, Cleansing abilities, and of course debuffs, particularly those related to morale, guilt, and shame. Also, powerful healing abilities. Possibly other powers in a PM if I feel up to it.
Oh yeah, he should be rather protected from Void influences, possibly as a byproduct of the method he cleans it away. AKA I don't want him dying instantly because the Void doesn't like my getting uppity.
((For comparison, if previous Void-cleaning abilities/angels have been brooms and mops, this guy is an industrial grade combination vacuum/steam-cleaner with customizable lye-pressure-washer attachment and cupholders))
