Bowyn is right, we are are all capable of murder under the right circumstances. I just don't understand people who say " I could never kill a person, they're either lying to themselves or just haven't been through the type of situation that drives you insane with: hatred, frustration,etc A quagmire of nasty emotions can set anyone off.
Crimes of Passion are the worst.
I remember when my former girlfriend of over a year gave me all her contact info, left for Texas, kissed me and told me she'd call as soon as she landed. I didn't hear for her for a year, she never came back. She wouldn't take my calls or contact me in any way. I was sick with worry, frustrated and completely devastated. I'd just sit there and listen to Ray Charles "
I Can't Stop Loving You" on rotation.
Because there was no malice involved, I gelt no I'll will toward her, but I wanted to kill myself, that's still violence. Thank God I had a very good shrink. It took lot's of therapy.
When my mother got sick, her boss wanted to fire her, simply for being I'll. This woman started a smear campaign against my mother, spreading lies such as her being a drug addict and worse. After she got fired, I really wanted to strangle her boss Ida's scrawny neck, have her die a slow and painful death at my hands.
Two things saved me: we were able to sue her company for damages for a hefty severance package and lifetime healthcare which I can use to, this lead to Ida getting fired herself. My mother recovered and was able to find a job just as good, but Ida is working currently for about half her former salary. This makes me very happy, therapy helped here as well.
Even as a child my paternal grandmother was abusive. She would steal my toys and take them to her home country, stole money from my family, destroyed my once close relationship with my father (he was also to blame) and would hit me with thorn branches (I hit her back
). I was six or seven and I had just lost my beloved maternal grandmother (it's so typical of my life to have one Angelic grandmother and another one who was demonic). As a child I actually looked for ways to poison her. I hope she rots in hell!
These emotions can take hold of you like a death grip and not let go.
Therefor when it comes to crimes of passion, I'm usually for "rehabilitation not retribution".
Note: I do not believe therapy is a panacea, it takes A LOT of work to find a good shrink.
