Proverbs 16:
The root of all evil.
"Pride goeth before destruction, and an haughty spirit before a fall." ~Pro 16:18
What was Satan's downfall? Hatred? Deception? A Murderous heart?
There's a bottom line, a "root" here that started it all. An "Achilles heel", if you will.
And that Achilles heel was pride.
He wanted to be "Creator", not the "created". He wanted to "de-throne" God, the Creator, and take His place on the throne.
And it is the same with man. Man wants to be their own "god". They would like to oust God. To "de-throne" God.
Here's the bottom line.
They "hate" God, just like Satan did, as Lucifer, when sin was found in his heart. By golly, man would "kill" God if they could. They already did, in essence, when they killed His only begotten Son when He was in the flesh. They came face to face with perfect innocence, and they killed Him, shedding His innocent blood.
Shedding innocent blood is nothing new. It happens every day. And it's perfectly legal. Man can, after all, make those laws that make it perfectly legal to shed innocent blood. And he already has.
And it all originates with pride.
Pride is the antithesis to love.
Pride isn't just Satan's Achilles heel. It's also man's.
That's why Satan fell. And man.
It is one of the 7 things that God hates.
And the very first one on the list.
"These six things doth the LORD hate: yea, seven are an abomination unto him: A proud look, a lying tongue, and hands that shed innocent blood, An heart that deviseth wicked imaginations, feet that be swift in running to mischief, A false witness that speaketh lies, and he that soweth discord among brethren." ~Pro 6:16-19
