The funniest joke of the last two millennia

Here is the funniest joke of the last two millenia: A Jew died for the love of Africans.

And no, he didn’t just die for only Africans who are alive today.
He died for all who died before him, after him and even those who are yet to exist – the nonexisting ones.

Ok, let’s just assume it’s not a joke, that everything is true. If he died to save us why is there so much evil in the world?
