@Tsukishima:
I am not saying Moria is alive for sure. I am just saying I think he is alive, he might be "dead", but it's really not sure, and the problem with the "Moria is dead" user is that they don't even contemplate the possibility Moria might be alive.
That said, Oda didn't create this situation only to kill Moria, but also to remind us that we don't know everything about the World Government, and that those guys aren't good people and won't tolerate failure.
Same as him. I addmit there are posibilities of him beeing dead,right now it even seems the most likely, and to be honest, I wouldnt mind at all if in the end he is trully dead. But knowing Oda all that I wanted to express is that he has probabilities of beeing alive, since the situation and details are unknown or ambiguous, with all of this situations till date resulting in the endangered character beeing alive somehow (In some case even by the grace of God, ask Pell). I will accept whatever Oda decide, just dont be surprised if we find out that Moria is hiding in Shabaody in a few chapters.
And Moria beeing alive wouldnt make Doflamingo nor the Gorousei or whoever asked him to do that less badasses. I mean, Crocodile apparently killed Mr.3, Chakka, and the Tsumegery in direct confrontation, and Kohza and Pell with his amazing plan. In the end, of all the named, only the Tsumegeri died, and because they comited suicide in order to fight him, not because of Croc. We could say exactly the same about Enel and the Shandians he attacked, like kamakiri, Laki or even Wiper, who turned out to be perfectly fine. Does those characters they tried to kill and ended up beeing alive make Croc or Enel less badass than they are?
Nothing exists; even if something exists, nothing can be known about it. Even if something can be known about it,
Not joining. 
Dead.
