Man is responsible because God calls him to account; man is responsible because the supreme power can punish him for disobedience. God, on the contrary, cannot be responsible for the plain reason that there is no power superior to him; no greater being can hold him accountable; no one can punish him; there is no one to whom God is responsible; there are no laws which he could disobey.
The sinner therefore, and not God, is responsible; the sinner alone is the author of sin. Man has no free will, for salvation is purely of grace; and God is sovereign.
That does it. God is good because he has all the power. We are told not to kill people because the most powerful being in the universe told us not to. But God didn't command himself to prevent killing and suffering, so he has no such obligation.
Gosh, I wish it were that easy.
