Why is Nelson Mandela worshiped so much in South Africa, or the world for that matter?

Since he took control So. Africa has went down hill, now the rape and AIDs capital of the earth, before him, 90% had elec. and running water, now only 40% and stores that were once stocked are now empty and closed, even UN convoys now have to feed them where as before they exported things. Most blacks and all Whites wish it was like before Mandela, I know, got African news site on here.
