Because the Creator is infinitely merciful and his intention includes nothing but good. An infinite Creator does not give paltry or limited gifts. He gives only infinite gifts. That we encounter restriction as we descend the tree is because there's a process taking us from infinite seed to infinite realization or fruit - from Keter to Malchut. The seven lower Sephirot represent the world of manifestation including the temporal.
Manifestation is temporary as is our suffering.
In contrast with the ultimate, infinite gift we are going to receive, all suffering is insignificant and will be obliterated. Divine Reality Chochmah is the active father, initiating principle. Chochmah includes the total idea universe of the cosmos. It is the fertilization of Keter's infinite potential. It is the beginning of all form, yet it is still formless.
