The prospect of butchering Tony into freezer-friendly joints was suddenly appalling to Rufus. He simply couldn't do it, not to this or any man. Nonetheless, he realised he had to dispose of the man fairly quickly. Rufus became stressed for the first time he could remember. He needed to unstress with Mac2.
Mac2 realised there was a problem. It did take some time for the machine to deduce what might be the root cause of that problem though. Eventually, it decided on another bout of reprogramming. Gay persuasion completely removed.
Rufus was a mankind hater.
Let the butchery commence!
