This is the same "evil" that is in the fruit of the tree.
There is no moral bias to the word.
Here's this verse from "concordant" versions of this verse..
Genesis 6:5
(CLV) And seeing is Yahweh Elohim that much is the evil of humanity in the earth, and every form of the devices of its heart is but evil all its days.
(LEB) And Yahweh saw that the evil of humankind was great upon the earth, and every inclination of the thoughts of his heart was always only evil.
(LITV) And Jehovah saw that the evil of man was great on the earth, and every imagination of the thoughts of his heart was only evil all the day long.
Try this: Just take the first five "definitions" (excluding 'evil') and read it that way.
(CLV) And seeing is Yahweh Elohim that much is the bad of humanity in the earth, and every form of the devices of its heart is but bad all its days.(LEB) And Yahweh saw that the adversity of humankind was great upon the earth, and every inclination of the thoughts of his heart was always only adversity.(LITV) And Jehovah saw that the affliction of man was great on the earth, and every imagination of the thoughts of his heart was only affliction all the day long.(CLV) And seeing is Yahweh Elohim that much is the calamity of humanity in the earth, and every form of the devices of its heart is but calamity all its days.(LEB) And Yahweh saw that the distress of humankind was great upon the earth, and every inclination of the thoughts of his heart was always only distress.Small wonder Noah built the ark.
Sounds like several things it's good to be saved from, if I lived in the days of Noah. I'd want to get away from that too, especially if the thoughts of my heart were true, honest, just, lovely--in other words, GOOD--or at least I wanted them to be. Come to think of it, I DID want them to be almost nine years ago. Somehow, despite all my "sin" and "wickedness", He's been my Ark.
Of course God completely failed to wipe out sin and wickedness (the KJV and it's 'followers' choices of words) from the face of the land by drowning all those folks. According to most, that was His purpose. The ark had barely landed before Noah and crew were at it again. On to Plan C?
Or maybe I'm just being cryptic and pedantic again.
