6.Have
you ever heard of an exorcism being performed on a psychopath? Do you think
this might be a viable option to try? (I mean in jail and not used as
rehabilitation for possible release.)


I have never heard any case of psychopathy being “cured” by any means. Since
psychopaths are not delusional, I do not believe that psychopathy can be
“cured” through an exorcism.  Although
there are occasional cases, psychopaths normally do not report being
“possessed” by entities, and even those that do, like Son of Sam, the Night
Stalker, or Danny Rolling, the sincerity of their claim of possession is in
question.  These kinds of “possessions”
are more appropriate to psychotics, but they rarely are functional enough to
sustain an organized serial killing career. 
Most psychotics are a danger to themselves long before they might
endanger others.    At the moment
psychopathy appears to be hardwired in the behavioral part of the human brain
and in males seems to diminish on its own with middle-age.  Why that is we still do not understand. 



7. Do most serial killers report that
they've had head injuries as a child?


A significant number (although I could not give you the exact percentage) report
head injuries as children.  The classic
1980s FBI Behavioral Sciences Unit study of incarcerated serial killers found
that 29 percent of serial killers were “accident prone” in their childhood, but
did not specify head injuries.  The
problem here again, is kids run around and fall and hit their heads all the
time.  I suspect that a large portion of
adults have suffered a knock to the head as kids without becoming serial
killers.    That is the daunting thing about serial
killers—their childhood histories are shared by more non-killers than killers,
thus again, that elusive X-factor is left unexplained.

8. Do you consider serial killing an
addiction?


Yes in the case of fantasy driven murders, especially sexual fantasy driven
murder.  The fantasy is that of total
control but it never is as satisfactory in reality as in the fantasy.  That is why many serial killers achieve a
sexual climax after their act, rather than during it.  The climax is triggered by the serial killer fantasizing the completion
of the murderous act as fantasized rather than as actually executed.  The serial killer is cyclically driven to
“perfect” his fantasy in reality, but is constantly disappointed either by the
victims’ refusal or circumstance to comply exactly with the fantasy or his own
ability to stage the fantasy in reality. 
The drive to merge fantasy with reality, mediated by disappointment and
the need to perfect the transcendence from fantasy to reality, is the addictive
key.

    9. Do you think there is always a
sexual release before, during or after a kill?

It ranges from serial killer to serial killer, but many serial killers are
unable to achieve the necessary level of control during the homicide to come to
a sexual release.  That level of control
may come only after the victim is dead or when the serial killer returns to a
safe and controlled environment, perhaps with souvenirs, photos or videos, and
achieves a sexual release at that point, often fantasizing that the murder they
had just committed had actually occurred as they planned and fantasized it
would.

10.Can a serial killer ever fall in
love or have an addiction to another person? When they marry and have families
can a serial killer give love? Do they fake it? What's the reason for marrying
and having children? To pass?


That is a recent debate I saw on the internet as to whether married serial
killers actually loved their wives.   If
fifty-percent of marriages are said to fail within 5 years, then you do not
have to be a serial killer to marry for the wrong reasons.  People marry for secure companionship or
because they feel they need to marry by a certain age to be like “everyone else.”  Psychopaths not only ‘manifest’ contrived
outward behavioral and emotional responses that they think they ‘should’ but as
well manifest certain conventional modes of life if they are to appear (or be)
normal, a pressure that we all feel.  
Many serial killers are capable of keeping a job and maintaining a
marriage outwardly because that is what they feel is required of them by
society.   They “fake it” to the extent
they can, going “through the motions” so to speak.   Serial killers with wives and children in a
compartmentalized part of their life, although not a majority, are not unusual
either.  
As far as I know, no concerted
study of serial killer spouses and children has been conducted, and the
difficulty there is discerning the serial killer’s capacity of deceiving their
partner with any spouse to recognize or auto-deceive themselves about the
context of their partner’s behavior.  I
always remember what Marina Oswald, Lee Harvey Oswald’s widow once said to me,
“The wife is always the last to find out.”
