Should Harold Camping just go kill himself already?

Like really, if he's really THAT into bible, then he should understand that "nobody but God knows the time". And yet, he makes the whole world go crazy saying that theres going to be the end of the world. HE can't know that...only GOD can. He's not God. This pisses me off that all of a sudden he decided that he wants more attention so he told everyone that the world will end. He might be mental, he cant say such things. If he's not sure(and he's not), then he shouldn't make the world to believe this. This is not just some small community we're talking about, its the whole world. Just because some 89 years old grandpa is into bible and said that the world will end, everyone should quit their jobs and believe this. Like really, shouldnt he get some type of punishment so he would stop making the world go crazy?
