God judges men from the inside out; men judge men from the outside in. Perhaps to God, an extreme mental patient is doing quite well in going a month without murder, for he fought his chemical imbalance and succeeded; oppositely, perhaps the healthy, able and stable man who has never murdered in his life yet went a lifetime consciously, willingly never loving anyone but himself may then be subject to harsher judgment than the extreme mental patient. It might be so that God will stand for the weak and question the strong.
When we find that God's ways always coincide with our own ways, it's time to question who we're really worshipping, God or ourselves. The latter moves the nature of godliness from the King to our servant to a slave, a deduction into the realm of selfhood and then the lower, slavehood. It's a spiritual mathematics in that men who need God in his godhood are humble yet strong and spiritually ambitious while men who need a slave in their selfhood are ultimately paralyzed and will remain paralyzed.
