That's a tough one. When Castiel mentioned that Heaven was in chaos, I can understand why.

For Raphael's POV, the Apocalypse was supposed to happen, and a couple of humans managed to stuff it up. But, because God said it would happen, Raphael chooses to try and get it kickstarted again, and because he's an archangel, most of the other angels believe that he's above reproach. So they follow him unquestioningly, believing in the words of their long departed father (whether they know he's gone or not) and their one remaining archangel.

With Castiel's POV, he'd been destroyed by archangels, and resurrected by a being unknown (but who he thinks may have been God) not once, but twice. For that reason, he believes that his duty is to keep the Apocalypse from happening again. He manages to convince a few fellow angels that if God truly wanted the whole thing to happen, then 2 tiny humans surely wouldn't have been able to derail it, and it would have happened. He knows how it feels to not be able to trust his superiors (Uriel being the first big betrayal and a major tipping point), and so he leads others down the path of 'doubt'.

TL;DR

If I was an angel, I'd probably follow Raphael. His reasoning is the most logical, especially for a group of entities that are not used to feeling confused about their purpose, which is to follow God's word. Of course, if it became widely known that Raphael, Zachariah and the others didn't actively attempt to stop Lucifer's release, I can see why some would have swung over to Castiel's way of thinking.
