In my country a man did exactly the same, however he don't claim anything, he do it without making any statement before jumping in, however there was no real interview after, so, maybe it's the same as this guy...
However he survived, the lions just store him as a snack, just a paw over him and he was defenseless as a baby, however he survived, as the lions didn't ate or harm him, the irony is that for the act he made it seems he wanted to die, but not suicide, even so he failed miserabily...unless he only wanted to drawn attention without harming anybody else...
