I hate to say it but this seems to be a strawman argument. It assumes that, if there is a god, then this god would have the same ideas about "evil" as us humans do and that he would want to eliminate it. There are any number of reasons that such a fictional being (if existing) would not give a shit about humanity or humanities' ideas. At best, the argument destroys the general claims that most religions make about their gods.
How shall we judge morality (~evil) except by human standards? If a god has non-human standards and is not benevolent, then why worship him? Pick a benevolent god if such there be.
Sure, a given god may be claimed to be evil, but that is not the point. Who would worship an evil god? Would an evil person?
There is a very small likelihood of the existence of the benevolent god described in the three Abrahamic religions--one worship-worthy.
In our experience almost all of the entities that judge morality are not evil. Given our prior experience with such individuals (using humanity as our guide) we submit to Bayes Theorem.
P(~evil judger) = 99% in our experience. Suppose that in our experience of (descriptions of) gods we find 1% to be evil (or tricksters). This parallels human experience quite well.
Now shall we calculate with a given "excuse" for an apologist's god being correct? The problem is that there are literally hundreds of
entirely different apologetics for any given problem verse. What is the probability that a given apologist is correct
and all the other apologists wrong is 1/(number of apologetics).
This actually lowers the probability of a good god. .99/(number of apologetics).
When there are a 3 apologists who disagree on a given apologetic the probability of a benevolent god becomes .33. When those same 3 differ on a different verse the probability of one of them being right is .33 x .33. Each different interpretation of another verse multiplies the probability by 1/3.
When those 3 disagree on yet another verse .11.
Consider the apologists for YHVH coming from the three Abrahamic religions, all of which claim a benevolent god and do the math.
