The best you can do is look at it like Job, whether you believe in God or not:
glad at your chance at life at what good you found in it. The non-believer who
judges that the bad proves there's no God, or ability to believe in God, given
the bad forces the point past Job's decision about as much as a believer would
be in judging that God is all-beneficent and be unwilling to look at the bad in
the world.
A non-believer can look at the bad in the world yet basically have Job's
outlook, so should see that looking at the bad doesn't preclude belief in God
but only an all-benificent God concept. And nobody looks around and sees we're
all living in heavenly circumstances forever.
To make an analogy between life and God, if you can look a the good and bad in
life and still believe in living then you can look at the good and bad God
allows and believe in a God that presides over it. Or not. But it doesn't
force the decision.
Putting God on trial in the sense of looking at the bad has been part of what
a believer does at least as far back as someone wrote Job. It's just something
believers and non-believers have had in common for thousands of years and hasn't
forced which of their choices to make yet, except both would be better off
basically looking at it like Job. (The Christian could add that their hope
includes God providing a good afterlife, and the Universalist even add everyone
going there.)
