How can you not see how those lyrics are emo?

"So cut my wrists and black my eyes"
It doesn't even get much more emo than that.

"So spill my blood (SPILL MY BLOOD)"
Emo.

As well as like every single line in those lyrics. I don't know how to explain it any further, its pretty much common sense to recognize what is emo and whiny and what is good.
