Crimes of Passion. I used to peruse used book stores attracted to titles around this topic. Having used up my ability to intellectually dissect any and all relationships, I had found myself fascinated by instances in which people simply lost their bearings due to love or jealousy or an overriding sense of justice that perhaps didn't fit in with anyone else's ideas, or even, up until their breaking point, their own.
Not only was I fascinated, I was mesmerized, completely dumbfounded by the illogical, irrational and messy emotional blizzard that people, myself included, experienced particularly when it came to love and sex.
The fact that the media has such a field day with it is partly a reflection of how badly we all want to see others in the throes of irrational passion and how confused all of us, all humans, really are. It's easy to pass judgement on others and makes us feel safe, smug, morality in tact, chin up, vows forever, stability rigidity and honesty, integrity, goodness, etc - it's what most of us, at least up front, strive for.
But it is possible for good, caring and otherwise morally sound people to fall in love and completely lose their minds. Sometimes it's lust, or sex addiction, or a whole host of other pathologies that can cause them to seek out dangerous or unstable situations; abandonment issues that cause them to find validation over and over in unhealthy ways.
But sometimes it's just inexplicable. The mystery of our irrational passion is one of the last mysteries left to us as people, and hence, I believe, our insatiable thirst to figure it out and watch its patterns played out; sometimes artfully and poignantly and sometimes with incomprehensible baseness.
