From the point of view of a crude barbarian, who's life consists generally of killing and being killed, the industrialized world is a shining heavenly utopia. To an angel though, the industrialized world is a dystopian pile of rotting corpse.

The angel wants to destroy it. The barbarian just thinks the angel is nuts. The angel wants to destroy relationships because they're all hollow anyway. And because apparently things need to get worse in order for there to be any chance of them getting better. Destroy all the light/hollow friendships. Remove all pretense of friendliness. Don't give people anything positive to hold on to, because all such is just lies. All such just takes away from The Truth. This world is dead, empty, meaningless, banal, pointless. This world must be destroyed.

But it doesn't need destroyed because it's already in the process of being destroyed. But the dying may take centuries. And during the long drawn out process of dying we are in a meaningless time, in meaningless lives.

Speed up the dying?

No. Because most likely what comes next will be even uglier and will also take centuries. There is nothing for it but that life is meaningless and empty. It is now and it still will be 40 years from now.
