These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Moral Event Horizon: Even with the lack of consequence, there is clearly a line the group is reluctant to cross. That is until Michael jumps right into the deep end of amorality, becoming a rapist and murderer in the process. They might not have to live with the world being none the wiser but, as it's pointed out, they'll still live with their crimes.
