Well actually me and my boyfriend talked about how to kill Caine. And he told me that God was punishing Caine with complete immorality, and the only want to kill him was to be diablorized. Because he can burn, but he can't die from it. And he has all the outputs of all the clans, except thaumaturgy and some assamitic sorcery.
Caine does have thaumaturgy per the book of Nod, yes, it is true that caine can be diabed, but no vampire can kill caine, because of methusulah level dominate which=controling all vampires from your blood
