Why Do the Nations Rage?

These are some of my thought while i was doing my devotions this morning. Psalm 2:1 asks,
Why do the nations rage,
And the people plot a vain thing?

The chapter goes on to talk about how the wicked attempt to stand against God's anointed, and God promises to/about His Son and the kings.

The first line of the first verse is what i was really focused on this morning. Why do the nations rage? Why do people stand against God? Why do we get so angry?

My first thought was that it's because they have no hope, but that sounded too much like a SundaySchool answer to me so i kept asking.
Because something is missing?
Because they/we feel the need to justify ourselves?
Because me, I, myself (pride)
Because sometimes the only way to stop guilt, feelings of hurt, emptiness, etc. is to turn those feelings into anger...
To make the internal, external.
To give an external source (???find something to lash out at???) to an internal source/problem (???an excuse for our own faillings and guilt???)

So now what? What is the internal problem?
In Psalm 2 those standing against God and His anointed say,
"Let us break Their bonds in pieces
and cast away Their cords from us" vs. 3
They didn't/don't like the Israelite's/God's rules & laws. They made them feel guilty (showed them their sins). ...removed their (self)justification & made them responsible for their own actions.
It's easier to offer a sacrifice to Baal asking for a blessing than to admit and acknowledge self-sin and a need for true repentance.

This is so much of a problem in our society today. What do you think?
