All of us are going to have the urge to kill, according to Dr. David Buss,
an evolutionary psychologist of The University of Texas at Austen.

Killing
is inhuman, yet it is becoming so common that it’s like punching somebody
playfully on the arm. Not to the dead person, it isn’t. Some of the murders,
in fact just above three percent, are caused by mating and love issues.

When
the mate of a person leaves that person behind, that person left behind is
more likely to kill. In other situations, if the spouse is being abused, for
long periods of time, they are likely to commit murder as well.

Of 429,729 murders, 13,670 were of a male’s wife. When men and women were
tested to see what made them kill.

It was shown that whenever a man’s wife
was disloyal in their love life, the man had an urge to kill the wife.
Whenever a man’s mating urges became urgent, he also had a high urge to
kill. Women had no urge to kill in these circumstances.

50% of murders are within two months of the couple’s split up. 85% of
murders are within a year. 88% of murderers stalk their wives before killing
them, but this doesn’t mean that so many stalkers are killers.

When a man is beat or surpassed in ability be another man in the fields of
work or love, they are more likely to kill. Women feel the urge coming on
after years of sexual and psychological abuse. In fact, 91% of men and 84%
of women have at least one fantasy of committing murder. 72% of all murders
are committed during homicidal fantasies.

All in all, almost everybody will
have an urge to kill someday, and it’s their choice to tame it or develop it
enough to actually kill.
