If killing is justified by an evidence-based predictive model, it's probably killing in the name of science. This would include the Vietnam war ("Domino theory"), the atomic bombings of Japan ("it will be less costly than invading"), and anti terrorist drone bombing ("they fit our proven terrorist heuristic")
I don't follow that line of reasoning at all. "Killing in the name of religion" would be to protect or spread some sort of metaphysical belief. The equivalent would be something like going to war with another country to build universities there.
Contrasting "scientism" as faith in "science" vs "science" as an evidence based process of ascertaining how the world works, you're probably describing "killing in the name of scientism" which is effectively religion insofar as it is a matter of faith.
E.g. faith that building universities and education makes people behave in a "sciencey" manner
