Games where evil playthroughs don't suck

[Norfleet]

I imprison them and then "repurpose" their bodies one limb at a time, ensuring they stay alive as long as possible. Is that still good?

Given that you seem to be trying to maximize their suffering in the process, without improving the efficiency of the process, not really. Disassembling them in one go is more efficient, and they won't feel anything because they will never wake up.
