I agree that's a moving target, but theoretically the shooter and the target (meaning both exist in society) are moving together.
Our Constitution is D-E-A-D, but words like "cruel and unusual" do drift and change meaning over time. Some change needs to be built in, and some things need to be made static. "Reasonable Person" does change over time, and that's a good thing.
As to burning witches; it is entirely reasonable to burn a Bride of Satan who casts spells that make crops fail, people fall ill, and who invites demons to possess her neighbors. The only reasonable course is to immediately destroy such a person with fire. Whether these actually exist or not is the question. How to treat them if they do is entirely reasonable!
