okay...
Some people are born evil is one of the most stupid phrases ever, nobody is born evil (what is evil anyhow) but human nature is complex and is formed by events and our daily life what we are exposed to what we see hear etc.
You look back in that child's daily life and i guarantee you there is some form of abuse happening in that family, I am talking about the boy here.
Stark you are a smart guy but this is not true at all. The situations in your life do forge the person too but are not the only thing that can forge a behavior, some behavior or psychological make up can be hereditary. I am 100% certain of this.
My word I am not lying about this story. My friend's dad adopted a 2 year old 30 years ago and he had 2 other children, all grew up in the same household, the 3 boys grew up thinking they where all brothers, no one knew the truth, the 2 blood brothers where successful, the other got into heroin and committed suicide. The Dad told the other 2 brothers that he was not related by blood. Finally they decided they needed to somehow find the adopted brother's real blood family, turns out they came in contact with the adopted kids biological ant (his Father's sister. And here is was she told them, shocking.....
She said her Dad was on heroin and commited suicide at age 28, her brother (the kids biological Father) was on heroin and commited suicide at 28 as well, so she continued to say that she wasn't surprised that the adopted child commited suicide after being addicted to heroin.
Don't tell me that was a fucken coincident either, there is traits you're born with and some people are born killers, some are born with a lack of empathy and some are born evil. This is a fact.
