I think that is an important point- that is to do any or all of the following:
a) separate a potential form of social darwinism that you described from the scientific theory of evolution
b) discuss limits of science to provide moral judgments
c) come up with a better way to apply the mechanisms behind the theory in a way that isn’t the evil eugenics/eliminate the weak understanding - perhaps like this report by the Evolution Institute: https://evolution-institute.org/wp-content/uploads/2016/11/2Social-Darwinism_Publication.pdf
In other words, in a similar sense to how the audience reacted to Peter preaching in Acts 2 more Christian voices need to come in and answer ‘what then shall we do now?’ (that is in the light of the scientific theory of evolution)
