Sorry for Everything I've Done [Galra!Keith fanfiction]

Chapter Three: Regrets

Common halfbreeds, whose other, non-Galran, heritage is not prominent, may be accepted by the pure Galra as the inferior fellow warriors, for their genome is quite strong and unconquered by xenogenes. The water-blooded halfbreeds thus, no matter how brave and glorious warriors they are, can't be accepted by the true Galra, for they're weak by their nature and their mixed blood makes them vulnerable. The only way to gain honour, respect and equality left for the spoiled halfbreeds is to go through "The Flame of Purification" and consequently either prove their strength or fall under the weight of their vulnerability.

   - So, it means... - started Lance in a cracked voice, but trailed off.
   - It means, - Coran continued in a low, hard and serious voice, which made Keith pop up his head and look into the Altean's eyes. It was horrifying how normally cheerful and a bit crazy royal advisor now sounded harshly and disappointed, but when their eyes met, stiff expression on Coran's face softened, and he gave Keith a sad sorrowful look. The prisoner's eyes widened in surprise. - It means all of you were really mean to Keith in some way.
   There was an awkward pause during which Keith carefully scanned through faces of those in front of him. Allura's eyebrows were furrowed as she stared angrily at her hands lying on her lap, Pidge hugged her knees, buried her face in them and breathed heavily, Hunk watched Keith from the corner of his eye, Lance's glare was glued to the floor, and Shiro... It was a pain just to look at him. When Keith met him in the eye, the Black Paladin's lips moved, as if he wanted to say something, but haven't got enough courage.
   Keith turned away. Now that Coran had said it, the midst in his head went away. He remembered everything.
When Coran spoke again, evil growl appeared on Keith's lips, showing white sharp-edged fangs.
   - You hurt your friend so much, that he started to hate himself and lost his mind. How could it even happen?
