In Majora's Mask, the scary-faced moon is always present overhead, looking down on Clocktown menacingly. Obviously, a standard moon does not show emotion, but this is no standard moon.
One of the first objectives in the game is to retrieve a "Moon's Tear", which we can see falling to Termina from the moon's eye. This is not proof, but could be an indicator that the moon might feel remorse. We also see at the end that the moon says
I...I shall consume. Consume...Consume everything.
This indicates some semblance of sentience in the moon. So, is it noted anywhere that the moon might feel emotion?
