[ WP ] And so he bitterly asked , `` Why ? ''

This is the second of any writing prompt I've written. Any feedback would be nice! 
 
 
 I toyed with him, dancing the knife blade on his skin. I felt satisfaction as he whimpered and cried like a little puppy.. He was tied up to the chair, blindfolded and gagged. I removed the gag from his mouth after some time, his muffled panting was n't giving me the same rush as before. Toying with him again, making very small cuts in his skin, I fell to boredom quickly. I needed something more, something satisfying. I pulled off his blindfold and his cold steel eyes met mine. 
 
 His eyes bore into my soul and he so bitterly asked, `` Why?'' 
 
 `` Why? What do you mean why?'' I replied. 
 
 `` You know what I mean by'Why' Barbara, do I have to spell it out for you, you bitch!'' 
 
 `` Keith... Keith, Keith, Keith.'' I said, backing away from him. I let out a sigh and quickly jabbed the knife into his hand. His screams echoed throughout the forest, birds flew away and animals scurried along from the magnitude of the sound. 
 
 `` Listen Keith... you were a nice guy. I thought we could get along well, ya know? Co-workers over in that quaint little diner. It's a shame though. You had to do it. You had to take the gun to her house? Alice was pretty devastated you know. She was broken when she came home and found out that her parents were dead. She went insane when she found her 8 year old little brother bleeding out!'' I said furiously, pulling out the knife and jabbing it through his other hand. His screams echoed throughout the forest again, and my sliver of care for him was the only thing that kept me from killing him right now. 
 
 `` I'm gon na make you suffer Keith. I'm gon na put you through 10 times more hell than Alice went through when she saw that grisly scene! I'm gon na break you Keith.'' 
 
 `` You're a real bitch Barbara. Do whatever you want to me. At least I'll die knowing that I made your life a living hell.'' Keith said to me. A smile crept onto my face. Fear fell into his eyes and he began to struggle. 
 
 `` I can do anything... right?'' I asked him, giggling like a psychopath. I took the knife and placed it slanted onto his skin. I dug it into his skin and slowly began to push the knife upwards. His screams were music to my ears and the look in his eyes was so, so, so blissful. I stopped for a moment until his screams died down to shallow breaths. 
 
 `` T-to think... I t-t-thought y-you were h-hot.'' he said. 
 
 `` Oh Keith.'' I said as I began to skin him once again. `` I'm going to avenge my girlfriend's family.''
