I would rather have nothing than have everyone be equal to me! - Satan/Lucifer

Satan, or rather, Lucifer, wanted to have God the Father's (my Heavenly Father and your Heavenly Father and Jesus Christ's Heavenly Father and Lucifer's) glory and wanted to take away our agency or force us to follow him, as well as hated Jesus Christ and His being chosen to carry-out our Heavenly Father's eternal plan.

There is a reason why the scriptures attest that in nothing is God offended but in our ingratitude.  Lucifer was a son of the morning and held some authority among God's children, but was so ungrateful that he wanted ALL of Our Father's glory--all of it!  Just so happened that he couldn't stand the thought of every one of His children having an equal opportunity to inherit all that the Father hath.  The irony of it is, that he tempts us to be ungrateful and inherit nothing--the same as he receives--so, all of Lucifer's or Satan's followers will receive the exact same thing: NOTHING!  In the end, his plan is carried out (by those who follow him).  Only, every damned soul that came to Earth will be resurrected and therefore have an Eternal body, which Satan will never have.  Ever.  I understand that Pride is the gateway sin to all other sins, but isn't ingratitude also?
