What will this be like?

Revelation 12:7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,

  8 And prevailed not; neither was their place found any more in heaven.

  9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.

When angels fight, is there pain?

They will suffer torment in the lake of fire, so do they not feel pain?

They don't die, but can they be hurt badly?

While they fight, can an angel cut off a finger of another angel?

When they are cast out into the earth, do they crash land?

Or, what if the devil uses that moment to deceive?

And descends slowly, feet first, upon the mount of Olives?

To counterfeit Jesus, and to deceive?
