I have always been very interested in how human mind
can work and act in some extreme situations; to be more specific, how it works
in the precise moment that a person kills another without any regret. There are
several investigations about if murderers are born with a kind of evilness in
their minds, or the society and different situations make them to kill.
A group of geneticists have discovered, in some serial
killers’ DNA, a rare condition in Y chromosome which they called “The evil gen”.
They identified that if a person has this condition, would be more prone of
being violent and having a lower I.Q. This discovers will lead several further
discussions about proving the bias of why some people have a major
predisposition for crime.
Otherwise, most scientists say that there not exists
such gen capable of producing criminal behavior by its own. They believe that several genes acting together,
combined with some social situations, could cause this violent attitude toward
other people. For example, if a person is born in a hostile environment; it has
a violent childhood; it was raped when it was a child; those entire situations
combined with this evil tendency could develop a bestial behavior, without any
guilt or empathy with any person.
So, do you believe
that a person could be born evil or is something random? Next time that you
feel a desire of killing someone, think about this, can you hold it or not? 
Very interesting! I have read about it too. I guess that what makes people evil is a combination of many factors like the ones you have already mentioned. Maybe a child that has the evil gene can grow up in an affable enviroment won´t develop a violent personality; on the other hand, a child that doesn´t have the evil gene could be moved to be violent by the envviroment in which s/he lives. Now, have you considered what might happen if this gene could be detected before the birth of your child... would you abort it??

DeleteConstanza, as you already mentioned it, a person who has the evil gene could or could not develop a violent personality, all depends on the social influence that the child may have during its childhood. Clarifying that, I could say that if I know that my child has the evil gene before the birth, I wouldn't abort it. That is simply because I know that I can provide him/her an affable enviroment to grow up.
DeleteIn this topic I would be strongly disaggre with the first statement, I think that believing that people have a "evil gene" it's a sort of pseudo-science, unlikely to be consider as a real fact; However there are some DNA features that turn people likely to be more violent but everything along the growing up process, I mean family violence or alienation are involve to produce a violent person.
