Where to begin? Criminals are people who have problems delaying gratification or thinking ahead to the consequences of their actions. They don't think ahead that far. Incarceration for extended periods doesn't seem like much of a possibility when they start. Also, a lot of them come from criminal cultures/backgrounds and don't consider other life options. And it's possible that if you can easily kill people, maybe conventional ideas of machismo don't matter to you.
I agree. When one looks beyond the glamorous, even noble veneer portrayed in the movies and television, one finds people free of inhibition when it comes to their own gratification. The sort of person that will murder on the slightest suspicion, or just for the fun of it, a person that will dismember a body, torture victims, savagely beat victims, engage in all manner of vice and whose thoughts are continually of evil is the type person in a given situation that may prefer a woman but will settle for a man.
