What is the actual killing?
The antagonist is fully acting on the plan to completion.
This may be one of the entry points for the protagonist as witness, secondary victim, or investigator.
Here, the antagonist either moves on in obscurity through successful planning, or meets with unforeseen obstacles through which they must play it by ear, or become ensnared in their obvious fulfillment of their motivation.
If the protagonist is involved, then the antagonist may be forced to improvise. The antagonist’s improvisations to ill-adjust the plan will undoubtedly include obscured, but personal characteristics that conflict with the details revealed in the crime’s commission.
The actual killing contains the basic elements of who, what, where, when, and why.
The who: The antagonist and the victim.
The what: Murder.
The where: Here.
The when: Now.
The why: The plan’s promise of relief.
All that is needed is for the antagonist to move away from the scene (fly, escape).
The antagonist is under the greatest stress of anticipation of discovery or capture. Thus, at the elemental emotional level it engages either anger or fear.
