Matt. 4:8-9

Hi freeatlast, in the parallel passage in Luke 4:

Luke 4

5 And the devil, taking him up into an high mountain, shewed unto him all the kingdoms of the world in a moment of time.
6 And the devil said unto him, All this power will I give thee, and the glory of them: for that is delivered unto me; and to whomsoever I will I give it.
7 If thou therefore wilt worship me, all shall be thine.​

Of course this makes the presumption that he was telling the truth which may very well be (the end justifies the means):

NIV 1 John 5:19 We know that we are children of God, and that the whole world is under the control of the evil one.​

OK, granted it was no temptation for Christ but that's all part of the tempt-test recorded in the Scripture for posterity's sake.
Perhaps the devil was not 100% sure that Jesus is/was the second person of the Trinity and had retained His holiness, especially having become flesh, a mortal human being. ​

The devil had won over a host of angels. Maybe his motto was "nothing ventured, nothing gained". He just had to try.​

Because Satan is the god of this "world". "World" meaning the whole sinful world system. In this sense Satan can give us what our flesh desires but it will end in death, for the wages of sin is death.
