Probably myself,

My first kill(except for a lot of birds with my pellet and a couple of hare's with my dad's shotgun)was blesbuck when I was about 10 years old.It was standing about 25meters looking straight at me and my late father told me to hit right between the eyes.I picked up the rifle and let it go but the blesbuck was stil staring at me.After a couple of seconds it trotted of in disgust and looked at my dad with a "what do i do now" look in my eyes.He just laughed and said go get it.I stalked it the best I thought and took a second shot also at the head not realizing the lesson my dad was trying to teach me.Lucky this time it entered just above the eyes and it dropped like a sack of shit.I was in my sweventh heaven.For the fifteen years after that up to now I learned a couple of lessen and luckily that shooting is getting better all the time.
But I think there is some worse than me.
