Buddha is on the side of the gods ?
I don't really think that he would want the extinction of mankind.
Adam, the first human, he actually is pretty unremarkable, he didn't do anything important except that he did the only thing that he shouldn't do and even so it was Eve who actually did most of the work, wouldn't Cain, Elijah, David or Nimrod be better in his place ?
Beelzebub being in the Gods side it's a surprise, he pretty much the Devil right hand, but most demons really want our eternal demise in religious text and stories, so it's not a big surprise
