Varying degrees of sinful craftiness in animals?

A seemingly overlooked passage in the creation accounts debate:

“Now the serpent was more crafty than any other beast of the field that the Lord God had made.” (Genesis 3:1)

The serpent’s craftiness is obviously a sinful craftiness. But not even young earth creationists seem/tend to think that other animals had varying degrees of sinful craftiness. “In the hierarchy of all animals, which have varying degrees of evil craftiness, the serpent was on top!” No.

Yet this is how Genesis 3 situates “the” serpent among others. This seems like a flag or signal that Genesis 3 is meant to be read a certain way. At the very least, not like a modern science textbook.
