For a Believer-
It is axiomatic with believers that God created/creates ALL life. That includes all life including humans etc., and also viruses, bacteria, prions, cancers. God designed DNA so that it often makes mistakes replication thus birth defects, cancers etc..
Reconcile 'Gods Love' with babies cancer. You cannot.
So God is the biggest killer of all. A Believer might argue that the Creator has the moral right to destroy its own creations. In that case even if you accept that, you are left with a God who may well be feared, but certainly not loved. Saying that 'God is Love' is probably the most inaccurate idiotic statement ever.
As an atheist I have no reason to be concerned with this nonsense. An atheist does not believe God doesn't exist. Once again I add this quote which I have never seen overturned.
"Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not willing? Then he is malevolent. Is he both able and willing? Then whence cometh evil? Is he neither able nor willing? Then why call him God?"
Epicurus circa. 250 B.C.E
