The Psychology of "Heaven"

So, follow me on this one: If Heaven exists then our existence is completely useless.

Here is my argument:

Assume that Heaven exists and that Christian believers are admitted.

Next assume that you are cognizant of yourself and others, and you still have your memories.

Lastly, assume that your personality remains intact, and that Heaven is "perfect".

Now, moving forward with these assumptions, being in Heaven implies a perfect happiness. But if you are still you, and others are still themselves, then conflict will still arise. Maybe you remember the robber that killed your spouse and then got "saved" and was admitted into Heaven, etc.

The only way to prevent this conflict is for God to "change" you upon admittance. So if a change would have to be made such that you don't feel sadness, anguish over a loved one not being in heaven, etc., then what was the point of your initial earth bound existence? Because if it's not really "you" in Heaven, then the whole prior life on earth was in fact pointless, God could have just made the heavenly automatons he wanted to begin with.

Because, here is a neat thought: The supposedly first two people on the planet had free will, and they fucked it up the rest of us. So to prevent that from logically happening again, your free will must be removed upon your heavenly admittance. So something somewhere has to give...

Chew on that one for a while.

Lastly, what happens to infants, children, or extremely old people? If you have the misfortune to die as a baby (but you have been baptised) then are you just this drooling, toothless lump for all eternity? Or if you elderly, are you then former decrepit shell of your former self for ever? These "little" details seem to have been conveniently neglected by the authors of this fantasy land.
