I usually don’t watch videos like this but was curious .... he definitely knew he had broken the doors (you can see into the shaft and the doors are kind of just hanging on the sides) yet he backed up to ram them again. That’s when he went into the shaft. All I could think of was the poor lady who had just used the elevator, but hopefully she went up instead of down so that he didn’t injure her.
Maybe he did think the lady was holding the door closed on purpose, but it seems there was a LOT of time between when she entered and the doors closed and when he appeared??
Hellevator alert
She does go down in the elevator. The doors have windows and when the guy first pulls up you can see the elevator descending through the windows.
