If there was no fall of man out of God's favor it means that the universe as it is now is as intended by God. It is full of suffering. Why would a loving God design it this way? It doesn't seem right. Christianity tries to explain suffering (but still fails in my opinion) through the fall of man.
Either way, if this God really cared surely they could have conceived a better design without the need to test us.
As brought out, this life is not always a gift to many. I have to take a high dosage of anxiety/anti-depressant medication just to function. The last time I tried to live without it, I had a severe, lengthy mental breakdown. Even now, on the medication, some days it is just enough to survive let alone enjoy life and see it as a gift.
I can't imagine what it is like for those even less fortunate than me.
