The Damaged (short story)

The Damaged..:
I thought u where dead, said the old woman as her husband pulled out a knife from his chest, bleeding still gasping for the moments so he could repay the favor before he past away, started walking even slower then before and holding the stained knife on his left hand, his wife sitting on a chair on the corner table and she wouldn't move, she thought he was going to fell on the floor moments before he could get to her, she had been planning this scene for a while now in her mind, she was tired, exhausted of playing the same scene over and over in her head, something snap in her, she was no longer the girl he once married and could no longer put together why did she do this, he said why did you do this, I am almost 95 I had a few years left and then I would be out of your life.
She immediately replies, you think I do this for me?
I'm doing this for you, I'm saving you the wasted years you had left, you no longer have to suffer waiting and thinking if this is going to be your last day, we are to old to do what we did before and the only thing we can do is walking from one room to another, nonsense he says you do all sorts of stuff and me too-please old man, I'm still surprised ur still standing. you where supposed to die in your sleep sort of, when u stab me of course I was going to wake up, he walks a little further towards the kitchen table and she starts wondering if he was going to fell or not, she knew she had stab him in a place where he was supposed to almost die instantly so she was pondering maybe she missed her target, she then realizes he's too close to her and still walking as she could she gets up and as she reaches another knife she has on the dispensary, she feels a big puncture on her back and a warm feeling covering ahead, she turns back and feels dizzy she sees her husband still very far from her, she sees no knife in his hand and immediately reaches her back feeling a tick and soft handle she tries to pull it out but the pain is to much, she sees her hands all covered in her own blood and feeling fainting, before she could fell on her knees he says-now you feel the same way that I feel, he spits some blood and falls on the kitchen floor, she tries to walk towards the living room in order to reach the telephone, he grabs one leg making her fall on her face, she faints and he closes his eyes, next thing he feels a heavy pain in his chest, he opens his eyes disoriented looking at a white ceiling, he was just brought to life by the paramedics who came to the rescue as soon as he made the call right after he got out of bed not knowing what was going to happen later.
He gets into a bed in the hospital and a doctor comes in, she asks "how are you feeling, you just got brought to life!"
He looks at her but he feels tired to speak, she nods as if she would understand, she gets closer to his bed and says "I'm afraid I got some bad new, your wife did not make it"
The authorities are outside and they want to ask some questions about what happen"
She turns around and leaves the room.
Two police officers come in and take a position from both sides of the bed. The one to the left starts talking and introduces both of them
"My name is John and this is detective Fern, we are wondering how is it that you both guys got stabbed, it does not seem like somebody tried to brake in and stab you two, so we were wondering if you could give us an inside on the events"
He looks at both of them and starts telling them the story, they both look at each other as if they couldn't believe how raw those actions where, they take note and leave.
A couple of days later they both came back and since he had no family and he was too old all they did was transfer him to a retirement home where he would spend the rest of his days.
he kept himself in solitude and would not speak to anyone he would just sit on his chair and look trough the window alone with his thoughts, some of the workers there said that he would always have the same expressions in specific times of day, some of them would say he was relieving it every single day since then...
