The Public execution might need some work, and yes I know that sounds bad even for a sex slave management game.
If you try to change the execution method, it sometimes defaults to drowning instead of say, burning or throat-slit. The text also implies its a easier death, but there no precedent or order to which death is more "easier".
Never tried the killing feature, as it seems pointless in the face of getting a free slave for a minuscule amount of bad reputation. It might be a good idea to make the consequences of saving or purchasing the condemned more harsh.
Love the Mod so far, this version seems a bit more stable.
