If you choose no, then suffering will continue to exist forever, but only finitely intense suffering(including extreme suffering). If you choose yes, then you will undergo infinitely intense suffering for TREE(3) years, then(after TREE(3) years of suffering are over), you, along with every other sentient being will permanently lose your/their ability to suffer. Any new sentient entity will also never be able to suffer. Suffering will become physically impossible(even in principle).
