Yes, but the word “eschatological” should really be avoided in regular online discussion, since it is obscure and can easily be replaced in this instance with “doomsday,” which everyone understands.
Of course, feel free to use “eschatological” when discussing Mahler symphonies, especially 2, 5, and 9!
Let’s throw 6 in there as well.
Who made you the obscure word police? End of world scenarios are not always Doomsdays, they could include salvation for instance, so it really is not synonymous with eschatology.
