Doom and Gloom

What is it in the human psychology that wants to see the end of the world?  Why do we want to see the apocalypse?   Do we just love to scare the hell out of ourselves?  Is it our cultures?  Is it bred into us?  Im not trying to say that we can not do better as a human race.  Im just questioning our methods as to how we try to put information out there for people to see.  Most things are done by people who are well meaning.  When a person doesn’t think enough people are listening to them then they start this doom and gloom narrative.  For the most part its picked up by other not so well intentioned people and they use it to manipulate.
