I believe it can happen either way.
Raised, it's the way how our parents or guardians raise and treat us while we're growing up that determines our mental make up when we get older. If you're raised not being told the word no, you're going to be greedy and think the world owes you everything. If you're raised in a violent household, in most cases you will then see violence as an acceptable form of punishment. We're only as good as the people we learn from.
Both. + It all depends who they hang around with.
The way they're raised. We're all born innocent with only our parents or guardians to set examples.
raised wich makes them bad
I believe that some are born bad and some are raised in a manner that makes them turn out bad. I think my father had some of both.
i believe the majority of bad people become that way due to environment. probably about 5% of them are just bad seeds.
Both, depends on the person
Mostly the latter.
Both...I don't think one can make a sweeping generalization about human behavior.
A little of both
Raised, look at Jeffrey Dahmer. His dad got him into bones, bones got him to roadkill, roadkill got him to humans and then it goes on.
