I try sometimes to answer this question on my own.
Kung pamilyar kayo kay Job, kung saan sinabi ni Satan na he can make Job turn away from God, so he made him suffer. But Job endured Satan's torture and he was massively blessed by God.
God also gave Adam and Eve free will. Ang kalayaang pumili. And they chose to betray Him.
So i think its the same case for us, we are being tested by the Devil. And God cannot stop it because it means proving the Devil correct. But dont worry for the end of this suffering is already near.
If you want more reading po i suggest Habakkuk 1:3, 2:2-3. Here's some preview
