Honestly I'd like to see an evidence-based comparison of who is "morally worse" between Sterling and Drew. I think people might be surprised due to their bias for the main character.
Interesting comparison... although it's worth thinking about, don't cut it off halfway when the bad endings happen, there would be no need to compare.
We haven't fully revealed Drew yet, so it's early to say who is "morally worse." you could say Hunter really tortured Drew, the same thing that happened to Sterling when he was turned into a girl, we just need to get rid of Sterling's confidence and then we can say that Drew and Sterling, unlike Hunter, think more about well-being and love, and small taboos of affection
Drew is even more experienced than Sterling, so it is quite possible that she has a lot of sexual past, so in this story no one is morally normal anymore
