Welcome to the forum. Christ was not forced to die. He gave His life willingly:
John 10:17-18>Therefore doth my Father love me, because I lay down my life, that I might take it again. No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.
Also, God does not edit revelations. Whatever is revealed first is from God. If Islam is a true revelation from God then Mormons also have a case. Christians existed hundreds of years before Muhammed, and Christians believed Christ was God in the flesh (otherwise why would Muhammed say Christ was not the only begotten Son of God).
Also, Daniel 7:13-14 prophesied that a son of man will have all power. Then Christ in Matthew 28:18 says all power is given to Him in heaven and on earth.
