There nothing of that sort of humans attaining demonhood.
Diablo and the rest of the Prime/Lesser Evils were good o'l demon lords of Hell of the bat. Allegedly they are consider the seven heads of Tathamet the Prime Evil who have become separate entities born from Tathamet's smoldering corpse.
There is no "confirmed" answer, but the Book of Cain relates a "Creation Story" which Deckard Cain suggests may be close to the truth.
Without rehashing the original story (go buy the Book of Cain at your local booksellar :p ) there was at one point a Seven Headed Dragon (not to be confused with Trag-Oul). When it died, each head became one of the seven Evils, the three Prime and the four Lesser. They are essentially the First Demons to have ever existed.
If you're interested in Diablo lore, I highly advised buying the Book of Cain. It's not a novel, so if you're not really into reading lengthy sagas you're all good. The book is more of an abridged retelling of the major stories and events of the entire history of creation, and is extremely cool looking :)
