Growing up as kids I had this friend who took joy in killing anything killable,from their 2 house dogs to setting traps for pigeons on the Balcony of their house.
When he catches them he would slaughter them with joy all over his face.
One time in our estate when we were twelve all the houses that had dogs where killed and when his mom was cleaning out his Grandpa's abandoned volks bettle they had in the compound, she found ears of different dogs nailed to a wooden frame like a trophy board.
Thou the parents changed schools and put him in boarding school whenever he came home on holidays, the estate was not safe for pets.
This was years ago,last time we talked I asked him about his killing expedition and he said and I quote " I have evolved into higher orders and only go for species of equal intellect".
My friend is a psychopath
Let me leave this here and not say more.
By the way he's still my very good friend
