Can you blame them all? They have been promised countless times that they would be in Paradise. No paradise is here. I believe some of them really don't believe it anymore. They have taken everyone's hope away. It's like telling your kid you are taking them to Disney for many years and you never do. After a while they do not believe you.
We see so many people who are depressed and some who can't even get out of bed. So much for the happiest people on earth.
