God made everything perfect until Satan decided to question his creation and use lies and trickery to convince hundreds of angel to follow him into destructions.
We already know from the bible that there is no truth in the Devil and he is the master of lies.
You need to understand that the vile actions of the Devil and the curse that it put into our world were the reason why Christ had to die so that we can be redeemed. God is never going to forgive Satan for what he did, and eternal damnation is Satan only reward.
Psalm 1 King James Version (KJV) Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful. 2 But his delight is in the law of the Lord; and in his law doth he meditate day and night.3 And he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season; his leaf also shall not wither; and whatsoever he doeth shall prosper.4 The ungodly are not so: but are like the chaff which the wind driveth away.5 Therefore the ungodly shall not stand in the judgment, nor sinners in the congregation of the righteous.6 For the Lord knoweth the way of the righteous: but the way of the ungodly shall perish.
