There has been a genre of horror movies where people try to prevent the End of Days by doing something to stop the Antichrist.
I had always thought those missed the point; it's not something we can prevent, but that's okay.
This may be a good time to back up and say what Latter-Day Saints believe. We believe that there will be growing wickedness and natural disasters -- things like you would read about in Revelation -- but then Christ will return and usher in 1000 years of peace.
We refer to the 1000 years as the Millennium. During this time people are resurrected and various things are healed. For example, my mother's first two children were born prematurely and died; we believe that she will get a chance to raise them. Also we believe there will be lots of temple work, going along with people getting the chances that they didn't have before.
These are generally thought of as good times, though I know people who are worried it will be the end of fun. I don't think righteousness across the Earth means that there can't be roller coasters and rock concerts, so that doesn't worry me a lot.
That being said, worrying about plagues and wars and earthquakes can be scary. I get people not looking forward to that part, though you could easily look around and say "Worse than this?"
And yes, at least for us, because even though I am aware of terrible things, I am sheltered from a lot of it. I imagine a lot of those buffers falling away.
From a spirituality/faith standpoint, those beliefs do keep me from total despair, though there are frequent waves of anger, sadness, and frustration.
Here's the thing that should be obvious, but maybe I am wrong...
WE ARE NOT SUPPOSED TO BE THE ONES CREATING THE PLAGUES AND THE WARS AND THE SUFFERING!
Just because there are apparently some higher-ups in the "Department of War" that don't get that.
First of all, Matthew 18:7
Woe unto the world because of offences! for it must needs be that offences come; but woe to that man by whom the offence cometh!
Revelation mentions the AntiChrist and the Beast, but that doesn't make them heroes.
Remember also the parables given in Matthew 25 as an accompaniment to talking about end times. They are parables given about those who are looking for His return. They talk about preparedness, but that preparedness is a matter of accumulating spiritual light, developing your abilities productively (which could be interpreted in a capitalist light if you don't take it in conjunction with all of the other scriptures), and especially feeding, clothing, visiting, and helping others.
Seriously, we are supposed to be feeding children; not bombing them.
I know you hear all of those stories about people who find the scriptures really wimpy but somehow think that's a different book... it's weird to me, but I believe it happens.
However, if you think bringing on the Second Coming is a good thing, and something you want to work toward, then please spend some time reading up on that would entail.
Remember what is written before those parables, in Matthew 24:22:
And except those days should be shortened, there should no flesh be saved: but for the elect’s sake those days shall be shortened.
It's not a laughing matter. It's not some macho fantasy. There are hard times right now, that we can expect to get worse, and we are called to make those times easier and alleviate suffering.
I know Raiders of the Lost Ark is fiction, but there is something real in the idea of Nazis thinking that if they wore the right outfits and said the right words they could have the power and glory.
Try and live in such a way that you don't deserve to have your face (and the rest of you) melted.
