In the view presented by the OP there is simply no reason for Christ to die. A suicidal display would make Christ mentally unstable, not loving.
Christ's death is a loving act only if it was necessary. The OP gives us no reason for Christ's death other than the Father decided that it was a good idea. This provokes no worship of Christ.
Once we see that Christ died as our substitute and that He bore the wrath of the Father that we know we deserve, then we respond with praise and thanksgiving.
Perhaps I didn't break it down enough in the OP. I apologize if my lack of articulation caused you to miss the reasons.
Christ died for our sake, for us. He became flesh to share in our humanity so that by His death He might break the power of Satan – that the prince of this world would be cast out and all men would be drawn unto Him. Christ had to suffer and die, to take upon Himself sinful flesh, and be raised to become the “firstfruits” of those who die. Since death came by man, also by man came the resurrection of the dead.
Again, sorry the OP was not complete enough. This is one reason for the thread, to compile my belief more completely in one place. I'm sure that now you can see why Christ was not "mentally unstable", why His death was necessary, and why He is worthy of all praise, honor, and glory.
Thanks again for pointing out the need to put the cookies on the bottom shelf. I took for granted several doctrines that you and
@Aaron were gracious enough to point out as absent. I hope this helps to clarify.
