Why does a clever Satan fight with God even though he knows he will lose? There was war in heaven (oh yes there was) and Satan lost his place in heaven when he was defeated. What biblical reason is there to show Satan's reasoning behind fighting with God (despite the fact that he knows he will lose)?
Since the Philosophy tag was raised. This is what I think.

Satan and the demons fear God. They are not going to fight against God. If anything Satan is out to get us. So is the antichrist who will trick us to fight against Christ Jesus.

He was cast out of Heaven. Luke 10:18 NET


  So he said to them, I saw Satan fall like lightning from heaven.


Satan did not even put up a fight. Here, he was simply thrown out. Ezekiel 28:17


  Your heart became proud on account of your beauty, and you corrupted
  your wisdom because of your splendor. So I threw you to the earth; I
  made a spectacle of you before kings


Satan is a liar, John 8:44 NET


  for he is a liar and the father of lies


At the battle of Armageddon, Satan will hide as we will be tricked to fight Christ Jesus.
I think this is how we will be tricked:
