The Albigenses found out, that like Buddha said, you can't think of God first before you think the question of why there is suffering at least generally.
Those who like Buddha are stupid humans that's why their bird size brain can never figure out why suffering exists. Then they try to fabricate whatever out of imagination and from their lack of minimal intelligence.
They failed to come up with a valid answer about suffering simply because wrongly assume that earth is the final place God tried to create. They are simply too human-centered and earth-centered to have assumed that all God's effort is to create a perfect world with humans in it. That's why they can never find a more legitimate reason why this world which presumably to be 'perfect' is full of suffering.
However, God (through the Bible) never said that He's going to make this world perfect. In contrary, after Adam leaving Eden, earth is a place of Satan. Adam and humans as his descendants are leaving outside God's realm. We are trying to make our way back. God's job on earth is no more than just saving the souls of humans. He no longer maintain anything else in this ungodly realm, not even the human genome.
Recently, scientists actually found that the Neanderthal genetic information can be located in our human genome. It says we keep screwing up human genes not only by marrying with close relatives, but also with other homo erectus such as the Neanderthals. God won't fix it for you as this is not heaven nor paradise. You are on own in terms of genetic contents.
Where ever outside God's realm should be full of suffering, including earth. Earth is actually a better place as God still has a job here which is unfinished, that is to save His Elect out. After this job is done everywhere outside God's realm will all be hell-like. That's why you are urged to get back into His realm (Heaven) before it's too late.
