"took a boy to the forest, slaughtered him with a scythe". I was kinda just thinking, but what if the 'boy' was someones heart, and getting slaughtered was losing the one they loved?
This song could tell different story for every person who listens to it and when they listen to it. A year ago, someone might think of a parent or someone when they listen to it. This year it might be about a guy/girl they love.
Basically, I think it's about someone you can't live without, someone who gives your life it's purpose.
