I don't think they focus too much on state of mind in crimes like these. If they do, it would be heavily weighted towards their initial crime. Keep in mind that they are still only looking at initial charges. They will likely change by the end of this.

I'll give you a better example. Lets say you get in a car accident, hitting another vehicle. The driver of the vehicle is injured.

Scenario 1: During the course of the investigation the officer determines that you committed no real crimes, ie. failure to yield. If you are found at fault, there's consequences but no criminal charges.

Scenario 2: During the course of the investigation the officer determines you had been drinking. You will be charged with DUI as well as felony assault/assault with a deadly weapon. If the other driver dies you will be charged with Murder 1/2. The DA will argue that the willful driving under the influence equates to premeditation.
