Why Define Good and Evil (Discontinued )

When you go into high school and become a freshman everyone gets sorted into categories the most common, Good and Light. The second most common being, Nature and Earth. The third being, Ice and Water, Fourth we have, Fire and Lightning and the least common one you don't see often Evil and Darkness.
Each category has a leader or God, they help you learn more about your powers you possess and they help even after they leave high school for at least till their out of collage. Now lets meet the Gods.
Luke he's the God of Good and Light.
Olivia she's the Goddess of Nature and Earth.
Barry he's the God of Ice and Water.
May she's the Goddess of Fire and Lightning.
And finally we have the most evil out of them all (at least that's what everyone else calls her)
Zemira the Goddess of Evil and Darkness.
Zemira and her best friend May got sorted into God categories together and since both of their powers work together it was easy to stay friends with each other. The hard part was, all of the people who are gods now were all friends, but after they got sorted Luke drifted apart from the group.
Zemira Had developed feelings for Luke but they were small and pointless so she let those feelings disappear.
But did they?

"OH MY GOD!" I started yelling "STOP DEFINING GOOD AND BAD!"

"I can't that's how we were taught Z you this" Luke replied

"Don't call me that" I said walking away
