Which could all be part of the motive like I said Jane?
This resonates with me Justice
"Most of their crimes are considered
'instrumental' - meaning they are committing the act for a specific reason. It tends to be planned, calculated and purposeful. They are not typically the group who will mindlessly commit a crime in a blind disorganised rage. They plotted, planned and possibly even stalked their victim. Getting away with it, cleaning up, and setting their alibi tends to be a part of such plans as well. Many of them will get away with their crimes. Quite a few can manipulate juries into believing their story and setting them free.
For instance a violent psychopath would easily commit violent crimes for the purpose of
punishing and domonstrating power over their non psychopathic partner. There have been individuals who have killed their own children as a means of punishing their spouse. Her
offence was filing for divorce and requesting sole custody. In his mind the
lesson was necessary. He punished her for slighting him. He regained his power position and hurt her in the process. You might wonder where is his guilt for killing his own children. There will be none. It was the
lesson taught to his wife that was important. The children were tools to convey his message and teach a
lesson.This is the coldness associated with a psychopathic crime.
