Answer

In my opinion, the Holy One, blessed be He, is not involved in the world today (except perhaps in sporadic and very rare cases), so the question does not arise. What was in the past? I do not know. Of course, one can still say that everything the Holy One, blessed be He, does is for the good—but He does nothing. In logical terminology, one could say that this is vacuously true (like the statement: all fairies have wings, which is also vacuously true because there are no fairies. The claim is that there is no fairy without wings, and if there were fairies they would have wings).
And on the practical level, everything depends on our own efforts, and we must fight against injustices. I should note that everyone would agree with that, of course, except that some would base it on the absurd and bizarre thesis of “human effort,” about which I have already written here several times in the past. See, for example, here, here, here and here (on “human effort,” see especially the third source).
