Drone stuff is sucha good subject of real meaty conversation.
I'll fully admit I take a lighter hand with depicting how intense the Korps methods can be, and I def do so with droning too.
Since MK is more heavily transfomation-themed/focused, drone stuff is like a more, full change, and I like going in to how that reflects on the Drone-ee's consciousness. I tend to depict it like a variable degree of compression of the drone's thoughts. MK Drones are a little more fluid in how Robo-brained they are and most still retain some spark of the Self within, just translated through drone thought.
But on the main subject of morality, The Korps in my writing definitely reserve sit only for consensual cases, Lighthearted Sexy Scenario TF Pranks, or cases of absolute necessity.
Dronification is a good immediate treatment for sudden physical or psycho-thaumiturgical damage from, say, incomprehensible otherworldly horrors.
But like, I definitely think they'd avoid using Droning as a nonconsentual weapon.
In the words of Site-003 Subcommander Eliza: "Droning is a privilege, not a punishment."
Like, mind zonking as a method of containing a captured Fascist Fuck or getting them to spill the beans or let them transport them to a more traditional method of containment, sure.
But full on Mind Prison? Honestly, I feel like even Proton would say it'd be more ethical to just put a bullet in his brain than keep him in I Have No Mouth territory. Just feels like a fucked up degree of perpetual unnecessary cruelty.
Plus I think nobody in the koprs would really like to know that the drone they're working alongside has a Nazi center. It would make things feel really awkward.
