As in part 1, I'll answer without
reading anyone else's response.
Question 1
I think there are 2 main factors involved that are also linked: empathy & boundaries.
The reason most of us dont commit heinous crime is not because its against the law, otherwise it'd take more than 1/2 of us in uniform to police &
jail the rest, but because we empathise with our fellow humans. We have a natural revulsion to causing suffering that we ourselves would understand. A
person who is abused will bury their emotions in an unconscious effort to protect their psyche &, in so doing, severely limit their capacity for
empathy. Without the understanding of just
how bad their intended action would make the victim feel, there is little inhibition except being
caught.
Also, if a person has been "taught" by life that the conventions of interaction, the boundaries of whats acceptable & where their or anyone else's
responsibility starts & ends, are untrustworthy, then they are not going to rely on them in forming a "moral compass". Again, what they can get away
with will be the most important factor.
Question 2
I would bet that these people are damaged in the same way as above. It need not have been the result of discrete traumatic events, but could be the
result of long term low level threat plus arbitrary &/or hypocritical treatment. I think that modern western culture provides quite a lot of that on
its own, throw in some confused, frustrated, possibly deluded parenting, & I believe a sensitive child will shut down well before any signs of major
problems occur. They would then grow up "acting normal" in order to avoid further threat, rather than innocently participating in life.
There's also physiological brain damage or congenital conditions to consider. If your brain isn't wired for empathy, you're just not going to care
about anyone else.
