God’s wrath is distinct from the final harvest, and humans dying is mercy, not wrath. Where a soul ends up is either eternal punishment or eternal reward. The wrath of God is only on those who reject God. The 6th Trumpet of 33% of humanity dying is not wrath either. Those who destroy the earth will be scattered among each group of humanity killed. To say a certain time period is only wrath is misleading. The 7 vials or bowels poured out on those at the end of Satan's 42 months, will be the full wrath, because only those destined for the lake of fire are alive. This set of judgments, happen while the 2 witnesses lay dead in Jerusalem for 3 days. They do not even happen during Satan's 42 months, but the 3 days, immediately following, because the 2 witnesses are the only 2 humans left during that time encouraging people to get their heads cut off, instead of receiving the mark. They are the only two witnesses period.
I have to assume you do not want any humans to die in the 4th Seal. The problem is that the fewer humans dying now, will mean many more will end up in the Lake of Fire, later. Teaching the Second Coming after the 7 years are over, has led many to think more people will turn to God and be saved. John never implies this false teaching any where in Revelation. Tribulation has been constant. We are to endure at all times over the last 1990 years. Enduring the final harvest was not the intent. Being raptured out at the Second Coming before the 7th Seal was the purpose of the church, and to take as much of the harvest as possible, before God on the throne and the Lamb even begin the final harvest. Then 25% of humanity dying will not be a big deal. 100%, of that 25%, should be the church, not lost souls. That is what the church should see, not 25% all unsaved souls.
Why was the final harvest of Jesus' first earthly ministry teachings, including the Olivet Discourse, not passed down as what John was revealing in Revelation? How did the church get so far off track looking for an individual AC, instead of God on the throne and the true Messiah? Paul says both appear in Titus 2:13-15
13 while continuing to expect the blessed fulfillment of our certain hope, which is the appearing of the Sh’khinah of our great God and the appearing of our Deliverer, Yeshua the Messiah.
14 He gave himself up on our behalf in order to free us from all violation of Torah and purify for himself a people who would be his own, eager to do good.
15 These are the things you should say. Encourage and rebuke with full authority; don’t let anyone look down on you.
Why did the church stop teaching both God in His Glory and the Lamb comes at the Second Coming. The only place that is found is Revelation 6:12-17
12 Then I watched as he broke the sixth seal, and there was a great earthquake, the sun turned black as sackcloth worn in mourning, and the full moon became blood-red.
13 The stars fell from heaven to earth just as a fig tree drops its figs when shaken by a strong wind.
14 The sky receded like a scroll being rolled up, and every mountain and island was moved from its place.
15 Then the earth’s kings, the rulers, the generals, the rich and the mighty — indeed, everyone, slave and free — hid himself in caves and among the rocks in the mountains,
16 and said to the mountains and rocks, “Fall on us, and hide us from the face of the One sitting on the throne and from the fury of the Lamb!
17 For the Great Day of their fury has come, and who can stand?”
All will see the Second Coming. Matthew 24:29-30. Jesus confirms both Paul and John that the Second Coming is prior to the Trumpets and the final harvest.
29 “But immediately following the trouble of those times,
the sun will grow dark,
the moon will stop shining,
the stars will fall from the sky,
and the powers in heaven will be shaken.
30 “Then the sign of the Son of Man will appear in the sky, all the tribes of the Land will mourn, and they will see the Son of Man coming on the clouds of heaven with tremendous power and glory.
The point of confirmation is both God on the throne, and the Lamb will be seen by all, and they come, together, to gather the final harvest. Many will fear, because they know their time is very short.
