You're right about columns, sometimes it's hard to see something behind them.
What about ending - it's a philosophical question. You've killed your rival, there is no enemies left, but you still suffering from bleeding and will die soon. It's a metaphor that every revenge doesn't change your life at all - it will just make you and other people suffer even more. Revenge - is worthless. No fancy endings, no credits, no applauds. That's the point.
We just don't have time to make proper ending
