Arguments in philosophy rarely achieve the status of full proofs, arguments that begin from premises known to be true and advancing by impeccable logic to a philosophically significant conclusion. Anyone familiar with my book on the argument from reason realizes that I do not make that kind of a claim on behalf of my own arguments against naturalism. Most of us think that it is a good day's work for a philosopher to provide a cumulative-case role-player, something that might "break the tie" if someone is on the fence between two positions, and in combination with other reasons, might provide a good reason for, say, believing in God or not believing in God.
The argument from evil seems to have a different status, at least in many minds. Many advocates of the argument from evil suppose that that argument, unlike your typical theistic on atheistic argument, really can stand on its own as a disproof of the existence of God, showing that all who believe in God are just being irrational. Plantinga is widely credited by both theists and atheists with showing that the argument does not achieve this goal.
Yet, I get the impression from some people that they really think that the argument from evil is something more than a cumulative case role-player, and I do not think that this claim is defensible. I am unsure as to whether the argument from evil can successfully play a role as a cumulative-case role-player, but I do not think it can do more than this.
At least what is known is the logical argument from evil (as opposed to the evidential argument from evil) was supposed to do.
Would anyone like to argue that it really is stronger than your average cumulative-case role player? That, virtually alone of all philosophical arguments, and regardless of all other considerations both pro and con, really provides beyond a reasonable doubt that God does not exist.
