Perhaps it's because of the bountiful legacy of their predecessors.
Perhaps it's because the social ecology of wizards is highly developed.
Or maybe it's just because of their well-fed idleness.
In the wizarding world, there exists such a group of people.
To them, magic based on the suffering of other beings is shameful and degrading. This highly selfish behavior that prioritizes self-interest should be eliminated from society. Good wizards must stand up and oppose this incorrect and evil action.
Are demons the enemies of wizards?
Yes, they are. But that doesn't mean they should be tortured and soul extracted for their blood. Even if the demons cook wizard babies into soup and turn wizard brains into wine, wizards must not resort to equally brutal methods against the demons.
"After all, we are wizards, we are good and righteous wizards."
