We agree that God is no monster, but that does not mean that He is anthropomorphic, either (Genesis, Judges, etc.).  The Father is not angry at all as He is impassible.  Jesus expressed righteous anger, once, in the temple precincts.  This does not mean that God does not discipline, or that He may be understood in human terms.
"AS A HUMAN BEING, Jesus did not know that he was going to die as he did."
Of course He knew (Lk. 9:22, 18:31 and 24:7; Mk. 8:31; Mt 17:22; Jn 3:14).  What else he may have known is speculation (did he know COBOL, quantum chromodynamics, the results of the seventh race at Hialeah today?) but His soul was always present to the Beatific Vision - He knew the plan and agreed with it.  He knew what was demanded of Him and asked if it was possible that the "cup would pass" - it didn't because, for reasons unknown to us, it couldn't.  That passion was the expression of His great Love.  God the Father gave up His Son to suffer and die that we might live (John 3:16).
