Killing someone with poison, by it's very nature, requires careful planning and subterfuge, so it comes as no surprise that poisoners tend to be cunning, sneaky, and creative (they can design the murder plan in as much detail as if they were writing the script for a play).
*Male or female, they tend to avoid physical confrontation and, instead, rely on verbal and emotional manipulation to get what they want from others.
Convicted poisoners*also tend to have a sense of inadequacy, for which they compensate through a scorn for authority, a strong need for control, wish-fulfillment*fantasies, and a self-centered, exploitive interpersonal style.
*Often either spoiled as a child or raised in an unhappy home, some*experts*liken the poisoner's personality to an incorrigible child whose immature desire for his/her own way leads him/her to try to control and manipulate the world.
*It's as if the poisoner never grew up and is determined to take what s/he wants just as a child would from a candy store.
*Developmentally stunted, other people are viewed without*empathy*and the poisoner's internal compass is guided instead by greed or lust rather than morals.
*And, because poison is often not detected initially, the power and control poisoners experience with success tends to increase his or her*confidence*in future endeavors.
