Satan wants to corrupt God’s creation, not just morally, that is easy to do. He wants to corrupt God’s creation physically. We are all created in God’s image.

Ezekiel 33:6
But if the watchman see the sword come, and blow not the trumpet, and the people be not warned; if the sword come, and take any person from among them, he is taken away in his iniquity; but his blood will I require at the watchman's hand.

Luke 10:24
For I tell you, that many prophets and kings have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them.

Proverbs 20:12
The hearing ear, and the seeing eye, the Lord hath made even both of them.
