We should appreciate things from God's perspective.

The Lord Jesus Christ, in Luke 19, pronounced terrible judgement on Jerusalem for its failure to grasp the seriousness of the occasion of his coming, and for their national rejection of him.

They had had such huge advantage in obtaining eternal life through the personal ministry of Jesus Christ among them in those days.  Yet as a nation they rejected him.  

Many, of course, did believe and were the early Christians and Church.  These were largely spared.

This Holocaust was accomplished in the horrific destruction of Jerusalem by Titus' Roman army in 70A.D.

The present West, Europe, the United States, etc., have had the huge benefit of the preaching and teachings of Jesus Christ through the Protestant Reformation. 

Yet, many have failed to take seriously Jesus Christ.

Additionally, acceptance of homosexuality, and of wrongful purposes and lives of men and women have become common.

So, God's serious judgement is fully due, and seems to be imminent.

As the legions charged in, neither persuasion nor threat could check their impetuosity: passion alone was in command. Crowded together around the entrances many were trampled by their friends, many fell among the still hot and smoking ruins of the colonnades and died as miserably as the defeated. As they neared the Sanctuary they pretended not even to hear Caesar's commands and urged the men in front to throw in more firebrands. The partisans were no longer in a position to help; everywhere was slaughter and flight. Most of the victims were peaceful citizens, weak and unarmed, butchered wherever they were caught. Round the Altar the heaps of corpses grew higher and higher, while down the Sanctuary steps poured a river of blood and the bodies of those killed at the top slithered to the bottom." 

³⁷ And when he was come nigh, even now at the descent of the mount of Olives, the whole multitude of the disciples began to rejoice and praise God with a loud voice for all the mighty works that they had seen;

³⁸ Saying, Blessed be the King that cometh in the name of the Lord: peace in heaven, and glory in the highest.

³⁹ And some of the Pharisees from among the multitude said unto him, Master, rebuke thy disciples.

⁴⁰ And he answered and said unto them, I tell you that, if these should hold their peace, the stones would immediately cry out.

⁴¹ And when he was come near, he beheld the city, and wept over it,

⁴² Saying, If thou hadst known, even thou, at least in this thy day, the things which belong unto thy peace! but now they are hid from thine eyes.

⁴³ For the days shall come upon thee, that thine enemies shall cast a trench about thee, and compass thee round, and keep thee in on every side,

⁴⁴ And shall lay thee even with the ground, and thy children within thee; and they shall not leave in thee one stone upon another; because thou knewest not the time of thy visitation.

⁴⁵ And he went into the temple, and began to cast out them that sold therein, and them that bought;

⁴⁶ Saying unto them, It is written, My house is the house of prayer: but ye have made it a den of thieves.

⁴⁷ And he taught daily in the temple. But the chief priests and the scribes and the chief of the people sought to destroy him,

⁴⁸ And could not find what they might do: for all the people were very attentive to hear him.
