Drugs- The anti-drug PSA and the bagged body struggling after I take his syringe, and injecting the "sick" door with an unknown substance, in reference to shooting up to "get well"
Voyeurism- both me looking into my neighbor's window and the all-seeing eye
Rape- knifing the vagina door
Pedophilia- our friend across the way with the small shadow in front of him
Sadism/masochism- our ability to stab the wrapped body for no gain, as well as the "no pleasure without pain" section of the gallery.
I'm sure I'm forgetting some, but there's also the journal entry referencing electroshock therapy, but I'm not sure if it's behavioral therapy or for fun. I was assuming it was corrective, and that the message telling me to indulge was in opposition to that, as if I was in treatment and fighting my desires to misbehave, and how I handle the door determines which of my behaviors I chose to indulge and how I feel about it.
On the other hand, that doesn't explain the anatomy references or the pesticide program, unless they represented a desire to murder.
Then again, I may have missed the mark entirely, because I couldn't identify the green organ (gland?) I'm stabbing in the non-stroke ending.
Edit: I just realized that the shadow could've been a camera on a tripod instead of a child, which would just make it another layer of voyeurism/watching.
Edit 2: I just realized it's a red room, not a triangular man in a red shirt in a window. I'm dumb.
