Natural laws are about describing how things work. Human laws are about preventing certain behaviors. They are different things.
Yes. But humans react to natural consequences by making laws banning the practice or practices that result in those natural consequences.
That is their experience but they don’t consider free will. The knights of the cross have a totally different approach in this.
True. We also know from Uriel that the exercise of free will is exceedingly rare.
And we don’t have that many examples of people trying to rehabilitate warlocks before they get too dangerous, only two, so I do not think we have conclusive evidence.
We don't, but it appears the Council does. I can't remember which book it was in, but I remember a discussion between Harry and another wizard about how the Council has tried to rehabilitate warlocks, and it never works. There was a line about how some appear to be on the path to recovery, but they always relapse eventually. I doubt they're making it all up.
Yeah, if the Merlin is to be believe the problem is they do not have enough wizards willing to go under the Doom with a troubled apprentice.
I don't think that's the problem from the Merlin's perspective. He did say that the Council didn't have the spare resources to allow a regional commander to split his time between mentoring and the war.
