I am a bit curious towards the interaction between gods such as Chaos, C'tan, Gork and Mork (Are they even real?), Hive Mind (though not a really a god it is considered to be as powerful as one). Has their been any interaction at all that we know of?

Looking at the gods do they have faults? I mean gods are supposed to be perfect, yet there is something that tells me that they are not. Gods, like other creatures still have emotion. That being said is it possible that through emotion they are able to screw up a perfect plan?

Also is their a possibility that a non-god can achieve godhood status? I hear of the possibility that if the Emperor dies he will become a god (and rightfully too! Hail the Emperor!).

Thanks in advance,
