Her words were calm, and gentle, attempting to reach through his vision's black haze of fury and soothe the beast within...as a fearful, yet patient mother might try to calm a raging child, to keep it from destroying itself or her...
...O, but his mind, his mind would not listen! He could not bid the storm of voices and thoughts be silent, could not bid his hand to free Emilia from its iron grasp. She was preaching to the choir, did she not realize? Perhaps he no more wished to speak to her like this than she wished to be berated and held captive, but what good could amenable sentiment do if his very self prevented him from acting upon it?
Besides the which...his anger, at that moment, seemed almost a shield, protecting from the crushing forces of Emilia's pity and his own despondent self-loathing. If he raged, he would not grieve, nor reveal any weakness of that sort withal. And if Emilia happened to be the one in closest vicinity, and stayed in that vicinity of her own accord, she willingly endangered herself. He would not be to blame for any harm that should befall her...
Curse you, wretched devil, for thinking such! Those justifications come not from a sound mind! Whatever harm befalls her will indeed be your doing, for it will be your hand wreaking it upon her! She deserves not this constant torment, no matter what you claim she has done! You will not heal your pain by causing it in others!
Ah, God, was it too much to ask to be free from battling one's own self? Enough...enough, I beg you... But he could not let Emilia see this. He had hurt her enough; better to leave her be and let the vile thoughts wear themselves out where she was not in danger of being hurt by them... So you will leave her yet again, villain that you are...
But he was, he was such a villain, and would do just that. "You are...you are in the right," he murmured, turning away from her, voice pained and taut. "You deserved not such treatment...forgive me. I must needs clear my head." And he walked out from the room without another word, laughing bitterly inside at the irony.
