All nonsense. With an omnipotent involved natural laws and consistency don’t matter. Nor is “the existence of evil” the issue; the existence of overwhelming amounts of evil and vast amounts of natural suffering it.
And I can tell very easily that this isn’t the "best of all possible worlds and never has been, because it can be and has been improved. That would be an impossibility in “the best of all possible worlds”, by definition.
And the “FWD” depends on using a nonsense concept to defend nonsense in nonsensical fashion. It’s gibberish that declares its own conclusion. There’s no “logic” to it, it is antithetical to logic.
It’s just an emotional appeal to the impossible concept of “free will”, to defend an impossible and evil god.
