"A man shall act as a man" is a decent translation, although it's a bit old fashioned and I might say "A human shall act as a human." However, it's important to remember that language is inextricably intertwined and while in English can certainly discuss the morality of humanity, innate compassion is not something we think of when we use this particular word.
