I find this difficult to understand. It sounds like a contradiction. For if the infliction of the suffering is morally justified, then the infliction is morally permissible. But if the suffering is morally evil, then its infliction is also morally evil, which is to say that its infliction is morally impermissible. But surely it is a contradiction to affirm of any action A that A is both morally permissible and morally impermissible.
If the suffering is morally justified in that it leads to a good unobtainable without it, then the suffering, though certainly unpleasant, disagreeable, repugnant, awful, excruciating, etc., is not under the conditions specified evil in a sense of 'evil' inconsistent with the divine omnibenevolence. It is instrumentally good. In the situation we are imagining, it is not only morally permissible but also morally obligatory for the parents to allow the painful treatment to be administered. This implies that the treatment ought to be administered. Therefore, if you say that the child's suffering remains evil despite its leading to a greater good, then you are committed to saying that the infliction of evil upon the child is morally obligatory, something that ought to be done. But this smacks of absurdity since it is hard to understand how any infliction of evil could be morally obligatory. Since in our example the infliction of suffering is morally permissible, I conclude that even intense suffering is not in every case evil.
What Rowe is saying is that suffering is intrinsically evil, and that its evilness remains the same whether or not the suffering is instrumentally good. What I am asserting contra Rowe is that whether or not an instance of suffering is evil depends on whether or not it is instrumentally good. For me, suffering that is instrumentally good is not evil. I concede of course that such suffering remains unpleasant, disagreeable, repugnant, awful, excruciating, etc. But I do not understand how suffering in itself, or intrinsically, can be said to be evil in circumstances in which it serves a greater good.
Perhaps the problem is that there are two senses of 'evil' in play, one non-normative (amoral) the other normative (moral), and that Rowe is appealing to the former sense. Accordingly, the non-normatively evil is that which elicits aversion. In this sense, mental and physical suffering is evil in that beings like us are prone to shun it. The normatively evil, on the other hand, is that which ought not exist. So perhaps the puzzle can be resolved by saying:
a) Every instance of suffering is evil in the non-normative sense that, as a matter of empirical fact, beings like us are prone to shun it.
b) Some instances of suffering are not evil in the normative sense that it is false that they ought not exist.
c) If an instance of suffering conduces to a good that outweighs it, and the good is unobtainable by any other means, then the instance of suffering ought to exist. Thus the child's suffering in our example ought to exist. Admittedly, this sounds paradoxical. But note that this 'ought' is not categorical but hypothetical or conditional: the child's suffering ought to exist given that, on condition that, the treatment that causes it is the only way to avoid the child's death, which would be an evil worse than the child's suffering from the treatment.
d) (c) is not paradoxical or incoherent.
e) The moral goodness of God is called into question not by the existence of evils in the non-normative sense, but by the existence of evils in the normative sense. Thus the mere existence of suffering, which is non-normatively evil, does not by itself cause a problem for the divine moral goodness. For it may well be that all instances of suffering are morally justifiable in the light of a greater good. This does not make these sufferings any less repugnant; but this repugnance is not a moral repugnance but the non-normative property of thwarting desire or eliciting aversion.
i) If God exists, then God is omnipotent, omniscient, and morally perfect.
ii) If God is omnipotent, then God has the power to eliminate all evil.
iii) If God is omniscient, then God knows when and where any evil exists or is about to exist.
iv) If God is morally perfect, then God has the desire to eliminate or prevent all evil.
v) Evil exists.
vi) If evil exists and God exists, then either God doesn’t have the power to eliminate or prevent all evil, or doesn’t know when or where evil exists, or doesn’t have the desire to eliminate or prevent all evil.
vii) Therefore, God doesn’t exist.
