Lecture you deaf

[Bushwhacker]

Three men are battling bizarre creatures in a pitch-black night. One of them is about to die by being bitten at his throat. But another fighter kills the monster before the disaster. In the process of killing the animal, the fighter loses the knife he's used because it has been left studded between the ribs, and being pitch-black there is not easy way to see where the animal is or has run to.
Aware of the lost, the fighter complains and says his trainer will kill him for it. But the fellow he's saved his life says to him:

-Lecture you deaf, more likely; you saved my life.

What might what is in black mean, please? I have not a clue.

Thank You

Note: The trainer is a forth person, not the victim. He doesn't appears in the scene.

Rather than reacting violently, the trainer will lecture him.
He will lecture him for so long (and so loudly) that the person who lost the knife will go deaf. It's hyperbole.

'in pitch black' means nothing but in dark night.

I think his doubt is about pitch black.
