Not according to the 5th seal. It only has the dead wanting revenge and they are told to wait for when their brothers will die as they did. Those shall die in the GT BUT IT'S A FUTURE EVENT. The seal is VERY clear that it describes a time BEFORE the GT.
The GT is not found taking place in any part of the 5th seal.
As I have said before, the 1st four seals are the beginning of sorrows in Matthew 24. The fifth seal is the great tribulation, shown in Matthew 24
15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:)
16 Then let them which be in Judaea flee into the mountains:
17 Let him which is on the housetop not come down to take any thing out of his house:
18 Neither let him which is in the field return back to take his clothes.
19 And woe unto them that are with child, and to them that give suck in those days!
20 But pray ye that your flight be not in the winter, neither on the sabbath day:
21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
The 6th seal is the coming of Jesus in Matthew 24, which we can also see in Rev 14
Revelation 14
14 And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle.
15 And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe.
16 And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped.
17 And another angel came out of the temple which is in heaven, he also having a sharp sickle.
18 And another angel came out from the altar, which had power over fire; and cried with a loud cry to him that had the sharp sickle, saying, Thrust in thy sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe.
19 And the angel thrust in his sickle into the earth, and gathered the vine of the earth, and cast it into the great winepress of the wrath of God.
Just because you don't understand this, doesn't mean it is not so.
