I killed a cat half dead from a car accident and my friend found out six years later

When I was 16, a cat was hit in the road near my house. It had already crawled onto someones front yard to die. It was in horrible shape, bleeding badly, broken legs, unable to move, and making the most awful sounds I have ever heard in my life. The owner was not around and I didn't want to leave the cat like that. I picked it up, took it behind my house, and shot it in the head with a 22 magnum handgun.<br><br>Six years later, my friend was showing a guy he was dating pictures from our childhood. In one of the pictures, I had a gun and the caption said first gun I ever fired. He asked my friend about the caption and my friend explained to him I used it to kill a cat that was hit by a car.<br><br>The guy I don't know was deeply disturbed by this and my friend was also messed up about it. From their perspective, I just shot a random cat for no reason and was taking pride in it. My friend hasn't spoken to me since the revelation and neither has his ex. It was completely reasonable to not want a still living being to suffer, but it appears that I was definitely in the wrong judging by the reaction.<br><br>Edit: i didn’t shoot random cat. Please see the post for the full story.<br><br>Edit2: i do not condone shooting random cats.
