3 days ago I was the victim of a break in. It was just after 10:30 at night. I was in my den reading a book. I heard a loud thud and a cracking sound coming from my back door which is just down the hall from my den. Then a second thud and a smash as the door was kicked in. I quickly realized that I was being broken into, at this point the adrenalin began flowing. I quickly stashed myself behind the den door and I heard footsteps coming down the hall. I held my breath and stood motionless as the figure came around the corner into the doorway of the den. I struck without really thinking, the primal part of my brain had taken over. I smashed the door into him as hard as I could. The force of the initial strike from the door knocked the kitchen knife he had been wielding out of his hand. It clattered across the floor and skidded under the desk. Taking advantage of the element of surprise I leapt onto the intruder, tackling him to the ground. As we crashed to the ground I entered a state of pure rage. I landed on top of him and the next few minutes are a bit of a blur and almost feel like something out of a dream. I know I punched him a few times in the face, he got a few hits to my torso as well. While we grappled I ended up in a position with my head in his neck. I remember letting out a sound I would equate to a roar and sunk my teeth into the side of his neck as hard as I could and proceeded to rip his throat out. There was a gush of thick warmth as I pulled away, the chunk of his neck falling from my blood soaked mouth. I remember being somewhat surprised by the volume of blood that spewed from his neck. I saw the look of shear terror and shock on his face. As if he had truly seen the visage of a monster. I slumped to the floor across from my foe, my gaze never leaving him. I remember watching him desperately, uselessly clutch at his neck as the life drained from him.He reached out to me, but I just sat and watched, fixated on the sight before me, my only thought was to wait untill he stopped moving. It did not take very long, couldn't have been more than a minute. As I regained my senses I was confronted with the realization of what had just transpired. There was now a corpse sitting in my den. There was blood everywhere, I was covered in it. I called 911 and told the dispatcher that I had been broken into and that I had killed my attacker. After the process of dealing with the authorities was all sorted out they told me it I was free to go. Although one cop told me that it was the most brutal thing he had ever seen after 6 years on the force. Now its a few days later and everything is cleaned up. My life has gone on as if it never happened, I went back to work today just fine. People keep walking on eggshells around me and treating me like I'm damaged or fragile now. Honestly I'm personally ok with what I did. This guy was a threat not only to me but to everyone in the neighbourhood. I was not his first victim and I would not have been his last. I removed a blight from society as far as I'm concerned. The other reaction I have been dealing with are the people that look at me like I'm some kind of wild animal, like I lost my humanity. I also don't think that's true, I may be an animal, but no more so than any other human. I don't really feel any different now than I did before. But now I'm curious and I would like to hear about other redditors experience being a killer and how it impacted your life and your view of yourself.
