Can a heart still break when it stops beating?

Quick note: there are hints of dissociation and existential conflict between organic/artificial life. I wrote this on a whim and thought about extending it, but it just hits a different note like this. Hope you like it!

"Is this really what this is about? Do you really think I would just stop 'caring' because of what you've done?" My voice glitched slightly at the sudden increase in volume.

She took a step back as I gestured exasperatedly in their direction. "Look-I get it. I came into your life and turned everything upside down, but you know what?" I stopped a few feet from her, before the lights behind my eyes dimmed down. "You didn't give me a choice!"

I threw an angry punch in their direction, just missing them by an inch as they jumped out of the way. "You're choices are yours, they have always been yours! I didn't want this-you brought me here, you made me into what I am!" Another missed hit, this time resulting with my hand running into the dry wall and leaving a superficial dent.

She stumbled out of the way, grabbing a chair and holding it in front of her protectively. "Y-you weren't supposed to recoil! Everything was how it was supposed to be, and you-!" She swung at me, nearly missing my shoulder. "Ruined-everything! You let the child get away, we only needed one more!"

There wasn't enough time to move when she backed me into the corner and landed a square hit into my side, sending me tumbling into the supplies of balloons, streamers, and party hats. Sensing she was going to try and hit me again, I sprung out of the mess, aiming for her legs. The momentum and weight of us both took us down abruptly, where it became a struggle to subdue the other.

"You killed me!" I screeched, grabbing their faux rabbit ears and slamming their head into the ground. "You forget that you have taken me away from my home, my family, my friends-and you have the audacity to blame me for your mistakes!?" I winced as their foot snaked under my hip before thrusting it outwards, throwing me off and landing awkwardly against the wall. "You can't erase what made me human-you can't craft people into machines!" I could hear the frustrated and tasking breaths from the other, their LED red eyes boring into me.

"If I had known you would have given me so much trouble I would have just left you to die! I saved you, gave you life!"

My body went rigid at their words, staring at them in disbelief. Seeing that I was stalled for a moment, they pushed themself up and steadied their hand on the table. "When I found you, you were barely conscious." Their voice was weak and clearly out of breath, as they held out a hand in desperate appeal. "You were so...broken."

My body hadn't moved, my eyes trained on the other as they subconsciously gripped their ribs.

"But I knew you could be fixed! I believed that you could be a strong asset, working with me." I flinched as they reached up and lifted their costume head, the voice no longer artificially grafted through the masks speaker. Venessa had her hair pulled back, streaks of blood still staining her cheeks as her green eyes softened towards me.

Feeling my breathing quicken, I struggled to stand as they watched with an unreadable expression, holding their headpiece close. "...you still don't get it. How could I even fathom taking someone else's life, just because you were selfish enough to take mine?" They bristled at my tone, watching intensely as I picked myself up, locking eyes with her. "You did this." My legs shook beneath me as I fell forward, shaking with anger. "The second you decided my organic life was over, the moment you saw me as a piece of equipment and no longer a human being," my voice cracked, artificial tears running down my face. "I died...I died...I died..." my voice glitched as my head sparked slightly, caught on a repeat. My mind was screaming, anger and disgust coursing through me.
