Satan/Lucifer is the deceiver, father of lies, and tempter.
He was thrown out of heaven, because of his heinous sin against God.
He (serpent) was cursed, as he deceived Adam and Eve in the Garden of Eden.
While Yeshuva was on Earth, his legion begged before Yeshuva not to punish them, and was thrown into some pigs.
His head was crushed onto the Cross by Yeshuva.
He will be chained for 1000 years.
Next he will be thrown into the molten lake of fire where he will cry out loud for ever.
That will be his END.
Satan is a foolhardy, and will remain as a foolhardy the world had ever known.
