The white-haired man quirks his head at the accusation, not fully grasping what Yusei is asking, because not a second later he answers earnestly; "Empathy is to experience emotions equivalent to those of another." He understands the definition, but little else.

His head quirks to an even greater angle when Yusei explains. For zaShunina, who views humanity as a whole and has difficulty seeing them as individuals, the idea that each is different and unique is something of a novel concept. He's aware of the individuality of people, but apart from those few who catch his interest, the rest tend to blur together. He only corrects the cant of his head and straightens up when the human finishes speaking.

"I see." He gives a single nod, as if confirming something to himself. "Empathy is a factor that can be disregarded if it would interfere with an objective." He 'hmm's softly--a tic he's picked up in his prolonged exposure to humans, and takes a step back, granting Yusei more space. "That objective is what you wish to know--the reason they would act against empathy to harm innocents.

I do hope you discover the answer you desire."
