why God made him appeared crucified?

The Qur'an doesn't state that God made it appear to the Jews. The Qur'an says "it was made to appear" and does not say who made it appear. Because the lie of the disbelievers became the standard narrative, it appears so [in history, the MAP of the past which is not identical to it] that the Messiah was crucified.

to the people who are being lied to by Paul et al, it is made to appear so that the Messiah is crucified — to those who followed him [the Messiah], they know that God Almighty did not abandon His beloved faithful one: they knew that he was not killed or crucified, and that Allah was directly responsible


furthermore, the meaning of YHWH is well understood according to the Tanakh and those who follow it (the Jews) to mean He Who is Ever-Living, Self-Subsisting; it is inconceivable that He should cease to live — likewise, it is inconceivable that He should be something created, or that the creation itself could contain Him. He is incomparable. [see: 1 Kings 8:27, Hosea 11:9, Isaiah 40:18]

so, while it would be the worst form of disbelief (polytheism) to believe that the Messiah is God — it would not be to have had the mistaken belief that the Messiah was killed and resurrected (instead of simply raised alive to God).
if someone did believe this mistake, then it would logically prevent them from accepting that the Messiah (who they think died) is, in fact, the Ever-Living.
it could be easier to (more immediately) convince them of the larger mistake (polytheism) if they had only heard that the Messiah never died.

however, this lie being the foundation of Paul's movement (which was separate from that of the Messiah's movement) did not lead its followers to worship the Messiah as the Eternal God until several more innovations were implemented and enforced. this was a consequence of Paul's movement
a) being separated from, and in opposition to that of the Torah [which the first followers of the Messiah aligned with]
b) being established with those to whom the Torah and its teachings [such as on God, on sin, on righteousness, on judgment] were and would be alien
