Behind the title of Guilty Crown

The Void Ranking System is intriguing in that I wonder how they’ll treat those with high ranked voids as compared to the lower ranked ones. Will the lower ranked ones be cared for since they’re “not as strong and won’t be able to fight” or will they be abandoned since they’re “practically useless if Shu can’t use them in battle”? Seeing as Yahiro is the one who came up with it, I’m thinking the latter will be more likely the scenario that plays out.

I started pondering about the meaning behind the series’ title, Guilty Crown.

Some of the lyrics:
This is My Guilty Crown
I’ll fight for what I believe
This is My Guilty Crown
I’ll fight with my friends to set my friends free
