The aliens are more clever than kind     i think this is the anwser

Answer 2

Answer:

  The aliens are without mercy.

Explanation:

  The author is using a metaphor. This is a figure of speech that makes a comparison between two things that are unrelated but share common characteristics.

  The heart is often used in literature as a comparison of emotion or empathy with others, so by saying that "hardened their hearts" the author is implying that they would no show mercy anymore.
