In Sayaka's case, I believe its an existential crisis springing from being in love, being a teenager and being a MG/Zombie that leads to a sense of inferiority. As a result it drove her to embrace her MG identity, which combined with her own strong sense of right and wrong reinforces her ideal of becoming a MG that uses magic for others. Unfortunately it leaves her in a fagile mental state that give way to complete despair as she is faced with the paradox of protecting a world that does not necessary deserves protection.
