Please don't take the way I will explain this personally; I'm only going over this slowly to be as clear as I can.
In order to be convicted of murder, one must have a specific intent; this is what attorneys call
malice.
Malice, for what you need to know here, is basically defined as a person's intention to do harm/injury to another party. In Kentucky, the
malice requirement for murder is this: "with intent to cause the death of another person..."
The exception, "if he acted under the influence of extreme emotional disturbance..." is a substitute for the malice I spoke of before. It means that a person did intend to cause the death of another person, but acted under what is more commonly called
heat of passion.
Heat of passion negates the malice spoken of before. Should you want to learn more on heat of passion, here is a link to a decent description:

If a jury finds one did act under extreme emotional disturbance/heat of passion, then the party would not be guilty of murder. That would not mean, however, that the person would not be guilty of any crime; "extreme emotional disturbance/heat of passion simply mitigates the crime of murder to manslaughter in Kentucky. It is not an absolute defense to murder, but only mitigates the crime (an absolute defense would be, for instance, self-defense). This is recognized in the language of the Kentucky manslaughter statute:
This absolutely is what the defense is angling for. Not guilty of murder, but he would be guilty of manslaughter. The only question the jury would be concerned with would be the malice requirement for the crime. No other questions would be needed. The only question that would need to be answered at trial would be "would a reasonable person in the same or similar circumstances feel extreme emotional disturbance to the level excusing a person from the murder."
