Clan structure

~Can someone who doesn't believe in StarClan become a leader?~

The young apprentice Moonpaw doesn't trust him. She becomes a warrior, deputy, and eventually leader of the Moonstar. But will StarClan approve of her? And if he did, he wouldn't be angry with her and the entire clan and the forest?

Can this situation be resolved somehow? But the Moonstar won't let herself be dictated to...
