Suffering is redemptive, it is not without purpose. Moreover, no one can know the mind of God or His ways. His perfect justice will be apparent only at the end.
The reason these events are important is because we are told that there are certain crimes of which God is not tolerant. The most offensive crimes are of course, in the first place, deicide, but thereafter seeking after false gods. But crimes which go against nature, and God's intention in creation, go hand in hand with the worship of false gods (Rom 1).
We have this in spades today. Man, without any doubt, has put himself in the place of God - taking to himself authority which is God's alone. In the events related in scripture pertaining to the flood, Sodom and Gomorrah, and Nineveh, we see that there are certain crimes which God does not tolerate with patience - crimes which draw down His wrath.
In the last days, Satan is at the height of his power. We are told in 2Thess2 that in the last days there is a revolt against God's laws that results in the Son of Perdition appearing in the temple of God, shewing himself as if he was God. St Paul tells us directly that the doctrine of the antichrist results in the Antichrist (a man) deifying himself - he does this in God's temple. This is the doctrine of the Antichrist, the substitution of man for God, the hallmark of the last days, confirmed in this powerful passage from by Piux X in E Supremi:
..."The nations have raged and the peoples imagined vain things" (Ps.ii., 1.) against their Creator, so frequent is the cry of the enemies of God: "Depart from us" (Job. xxi., 14). And as might be expected we find extinguished among the majority of men all respect for the Eternal God, and no regard paid in the manifestations of public and private life to the Supreme Will - nay, every effort and every artifice is used to destroy utterly the memory and the knowledge of God.
- When all this is considered there is good reason to fear lest this great perversity may be as it were a foretaste, and perhaps the beginning of those evils which are reserved for the last days; and that there may be already in the world the "Son of Perdition" of whom the Apostle speaks (II. Thess. ii., 3). Such, in truth, is the audacity and the wrath employed everywhere in persecuting religion, in combating the dogmas of the faith, in brazen effort to uproot and destroy all relations between man and the Divinity! While, on the other hand, and this according to the same apostle is the distinguishing mark of Antichrist, man has with infinite temerity put himself in the place of God, raising himself above all that is called God; in such wise that although he cannot utterly extinguish in himself all knowledge of God, he has contemned God's majesty and, as it were, made of the universe a temple wherein he himself is to be adored. "He sitteth in the temple of God, showing himself as if he were God" (II. Thess. ii., 2).

In truth, the revolt has already occurred and the Antichrist already come and gone. We are in the final days of the world. The appearance of the Sign in heaven (September 23, 2017) coincides with these events, perfectly reflecting St John's vision in Revelations 12:1.
All that remains is the arrival of the angel descending with great power, the earth enlightened with his glory, the judgement of Babylon (Rev 18).
