The Doctor is the third major enemy in Little Nightmares II, but you don’t encounter him until later in the hospital. While working on his grotesque life work, the doctor cares very much about his patients, and he won’t accept anything less than perfection. Even in the morgue, the doctor does his best to keep his patient alive when Mono shuts the power off.
There’s no real reason to believe the doctor is doing anything but minding his own business except for when he grabs Six and Mono if he discovers them tampering with his work.
However, at the end of the hospital is when the Doctor gives chase to Mono and Six.
At the end of the chase, Six suggests mono jump into the incinerator.
The doctor will jump in to chase after Mono.
However, there’s a small opening for Mono to crawl out of as the pair traps the doctor inside. You can pull the lever down and kill the doctor by burning him alive, but do you need to do it to progress through Little Nightmares II?
If you felt you were wronged in some way by the doctor, you can torch him. Six will watch his death through the small hole as he burns alive. However, if you have a soft spot in your heart for a man who just wanted to focus on his life’s work, you can keep him trapped there and continue on to the elevator in the background.
So if you’re wondering if you can spare the Doctor in Little Nightmares II, yes, you can.
