Which detail from the text best supports the author's perspective that the museum guard is too strict?

The detail about the Nazi prison guards in paragraph five contributes to the text because it shows that the guards had empathy towards the Jews. The article defines empathy as "...the ability to understand and share the feelings of another person." (Info Paragraph) In the article, it says, "...Nazi prison guards sometimes wept as they mowed down Jewish women and children, but they still did it." (Paragraph 5) The guards indeed felt terrible but their empathy didn't stop them from following orders. In conclusion, having or showing empathy isn't clear to "... actually [motivate] you to take moral action or [prevent] you from taking immoral action." (Paragraph 2)
