You were walking, exploring a new company when you spot a odd looking door with an un clear sign plate

Curiosity takes over and you step inside regardless of what the sign had said

It seemed pretty dark, with a few dim lights, you walked further down the corridor when you hear an sort of sound

You peeked around the corner seeing a tall man dressed in something all black hurting a person, he didn’t look quite young but still fragile and thin torturing him.. of some sort

Soon the man leaves, seeing him curled up into a corner almost hiding himself, what could he possibly had done?
