I'll agree with most of what you're saying, avoidance, de-escalation, other options.
I disagree that the deployment of a weapon should be the last resort. That statement always implies that the person should first apply or attempt to apply lesser means before going to deadly force. That's not always a viable option. You may not be able to safely withdraw, use persuasion, non-lethal physical force or other techniques due to the speed of the attack, determination of the agressor, or physical abilities, to name a few.
Each situation is unique unto itself and can only be assessed by the person involved subject to a review (investigation) by the police and prosecutor. Absent political or agenda driven motivations, as long as the use of force meets existing legal standards and the person has acted reasonably under the circumstances, "woulda, coulda, shoulda" doesn't matter.
This most certainly depends upon the jurisdiction. In California one is expected to take a beatdown before resorting to lethal force (drawing a weapon). Know the legal standard in your location, and the locations you visit.
