Yep. The modern fantasy author's version of this regarding slavery, "Chill bro. It's fantasy and my MC is a good-boy hero, surely he must end dat evil slavery bizness no?"Chill mate, it's a fantasy world.
It's like....do you read ANYTHING educational/academic? Do you NOT realize that in reality, you just doomed a shit load of people by destroying slavery in their society? ....And I'm not talking about the slaves either. People that have nothing to do with it, following the inevitable MASSIVE backlash to the economy, THOUSANDS at a minimum, will starve because of your forced altruistic ego-masturbation, at least until things stabilize and an alternative is produced. But if no alternative is produced, or it takes many decades which is a very common realistic outcome in these scenarios....well you just killed the very civilization you were trying to "improve." Or at least weakened it so severely that the neighboring kingdoms are definitely going to take advantage of it.
Nice going Hero.
