Okay here is my attempt at re writing this chap.
The moment that the he was alone with young Bakugo, he stared down at the teen with an oddly calculating glint in his blue eyes before finally saying, "When I agreed to come in and speak to you today of the events that have been taking place for the last few months, I expected many things when I walked through that door," He said as he indicated towards the door behind him before slowly continuing to speak. "Fear. A small sliver of guilt perhaps..."
Bakugo merely snorted from where he lay on the floor and said in a very clear tone that set Toshinori's teeth on edge, "I've got nothing to feel guilty nor scared of. You're a hero. You're job is to protect. And as for any guilt, I was doing Izuku a favor- putting her in her place. So you and everyone else are crazy if you think she'll let any criminal charges stick long enough for any kind of conviction."
"Is that so?" Toshinori wondered aloud, sounding none too pleased with the prospect of the boy going free as he turned the teen's words over in his mind.
"Yeah, ya see the bitch thinks I'm her friend. As long as she thinks that she won't do anything to jeopardize that."
"What makes you think that she still feels that way?"
"Because she needs me." Bakugo said with a twistedly gleeful grin that made Toshinori want to strangle the boy.
"You said that you were putting her in her place before? And tell me young Bakugo- What exactly is young Midoriya's place?"
The teen gave him an insane looking smirk and merely muttered, "Where I put her. Straight on her knees," Toshinori's countenance shifted and became positively frigid as he stared down at the boy while he continued to speak. "Did you know that she was in love with you?"
The sudden shift in conversation threw him a little bit. But he did his best not to show this by looking away from the boy for a moment and merely saying in a slightly curious tone, "Oh?"
"Yeah. The little bitch has been hot for you since she hit twelve," Toshinori cast him a strange look and resisted the urge to inwardly cringe at the mere thought of his innocent heir being 'hot' for him but said nothing as the teen continued, "But she was in love with you way before then. She just didn't seem to realize it."
"And you think she does now?" Toshinori asked, finding the idea of Izuku being in love with him now that she really knew him, somewhat ridiculous.
Bakugo snorted in disdain, his smirk growing somewhat as he said, "I know that she does. I've never seen her watch someone else the way she watches you. Hell she doesn't even look at other boys like she looks at you. To her you're like some god. She fucking loves you so much that it's literally sickening just to be near her when she see's you."
"And this has something to do with what you have done...how?"
Bakugo snorted at his words before saying, "It has everything to do with it," At those words Katsuki suddenly found himself the center of Toshinori's undivided attention. "She wants you. The greatest hero of all time to notice her, realize what she feels for you- and maybe even feel something in return for her. She wants you to see her as someone worthy of you. You're time, you're effort, your love and devotion..."
"And now, because of what I've done to her- she knows that you'll never look at her like that. You'll never care for her the way she wants. And why would you when you know that your so much better than she is? After all, she finally knows what her real worth is. And it isn't as a hero. And it's not as your girlfriend either. She's just some whore that's desperate to be used until there's nothing left. If anything, she should be thanking me for the lesson."
It was at this point that Toshinori couldn't stand to hear anymore and glanced at the door as he debated on whether or not he should leave when he heard Bakugo say, "I'll tell you this though- I can't wait to get out of here and get her alone again. Maybe this time I'll lock her up in the dungeon that I made for her. She'd have everything that she could ever want there. Including all the dick she could take."
Toshi fisted his hands at his sides and made a low, threatening sounding growl in warning. Something fierce stirred within him as he half continued to listen to the little monster speak.
He didn't want to hear the boy anymore. However for some reason he found himself rooted in place instead of walking away and leaving the little bastard to rot. No- instead of walking away, he simply stood there and let the nearly overwhelming urge to reach out and snap the teens neck wash over him as the boy continued to drone on and on until something in him finally snapped and he lashed out without realizing it.
The all too familiar sound of flesh hitting flesh, coupled with a pained cry jolted him to his senses, but only just a little bit as the door opened and he suddenly found himself being pulled off of the whimpering teen by several officers as he snarled, "You better get comfortable you son of a bitch- because you'll never see the light of day outside these bars again! Do you hear me? Never again!"
