Thank you everyone for sharing!
Several people have stated that one needs to define "good" and "evil" before this discussion can be relevant. This is a red herring (dragging a smelly old dead fish over the actual evidence and/or argument in order to draw attention away from the argument) and I'll show why. No matter how broadly or how narrowly one defines "good" the opposite which is evil will be only the opposite of how "good" is defined and can be nothing more. "Evil" will not be part of any relevant set unless it is the exact opposite of one of the definitions of a set that is called "good."
I'll make it even more clearly understood than that: suppose that "evil" is defined as someone who shoplifts, and that is the end of the definition about evil. Therefore, by definition "good" could only mean someone who never shoplifts, and by the strict definition of "evil" it means no more than that. That being the case, my question still has merit: are people "born" with the tendency to shoplift, or are they "born" with the tendency not to shoplift?
Those of you who are stuck on the meaning of "evil" and/or "good" are missing what I'm asking, because I asking about a concept for which strict definitions do not apply: only the fact that opposites do apply to every aspect of human existence. If anyone dares to challenge me, then name any noun that you think does not have an exact opposite and I will name it's exact opposite. I guarantee this.
Many fine people have said we are not "born" as good or evil. We are just "born." However, the facts show that some people who are born into the best and most loving of famlies, and have the best and most loving friends and lives as they grow up, then turn into evil people despite tons of love and nurturing throughout their lives.
Why? Someone said I was just trying to argue. I'm not. I'm trying to learn and maybe some of you people can teach me.
What say ye? Again I ask this.
