Lyric discussion by sokorny 

I get the impression that someone cheated on the narrator ("A cheater, you thrive on lechery" ... lechery is similar to lust).

So the narrator is angry at the cheater (who they feel have betrayed them). But they won't let it bring them down, they be stronger because of it.

Creonte is a Brazilian JiuJitsu term used to describe someone who switches allegiances (i.e. a betrayer).
