Well, yeah. I'm sorry it worries people, too. I'm sorry I have to share the planet with people who believe it is in their interest to bring about the End Times. But, then again, you're ok with that behavior?"End Times" began with Apocalyptic literature about a century before Christ. It was based on the idea that there would be a great leader who would make Israel a light to all nations. However, the realists at the time noted that humans were not capable of holding anything together for long. They surmised only God could do that. John's Book of Revelation was about first century issues, and once more was written in Apocalyptic literature format.
In any event, from a century before Christ, right up to the present, there have always been people convinced the end is near. Each generation goes through tough times, we all make it through. Personally, I think those who lived in the 1300s had the worst of it and had more reason to believe "End Times" than anyone else. I don't give it a second thought and I am sorry it worries so many non-Catholic Christians.
