Jealousy and Back Biting is Demonic

Do we understand that jealousy, envy and back biting is demonic, not to mention irrational?

James 3:16
"For where jealousy and selfish ambition exist, there will be disorder and every vile practice."

James 4:2-3
"You desire and do not have, so you murder. You covet and cannot obtain, so you fight and quarrel. You do not have, because you do not ask. You ask and do not receive, because you ask wrongly, to spend it on your passions."

James 3:14
"But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth."

Proverbs 14:30
"A tranquil heart gives life to the flesh, but envy makes the bones rot."

Proverbs 27:4
"Wrath is cruel, anger is overwhelming, but who can stand before jealousy?"

James 3:14-15
"But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth. This is not the wisdom that comes down from above, but is earthly, unspiritual, demonic."
