Do you think they are just lonely, cold, sad or just tired of living their life?
Why do people take the time to go out of their way to figure out when it's going to end? Didn't God just want you to LIVE your life and not worry about the end of times? If people sit here and worry when it's going to end, they won't be living a life anymore, instead they will live out of fear and do things on purpose to "be good," in a sense?
Or do you think they just want to start a cult/conspiracy to gain attention from people? Like didn't Harold Camping get over two millions dollars for the End of the World theory of today?
I think these poor souls just have nothing better to do and they despise their own lifes in this world and they feel the need to take it out on others. I think they are unhappy. I think they have had troublesome problems within their own family/relationship and they see other people being happy so here I'm going to predict the end of the world to make other people live an unhappy life like me.
Oh please, go listen to some "Till The World Ends" and dance and have a few drinks. Life is not that bad...
