Blood on the Ground Lyrics Meaning

HMMmm, I gues it can be interpreted in many ways! To me it's about a breakdown of a relationship and his afterthoughts..
"I don't wanna talk......." may have reference to the fact that he was sick and tired of trying to sort out issues/problem's in the relationship to a point where it became a release of a manifestation of anger and frustration where so hectic ( and maybe regretable ) stuff was said.

next stanza gives an explanation as to how hard he tried to make things work ("I've slaved........")and why he's so fed up/pissed off at what happened. And finishes off with the ultimate of insults "Cause something inside of me has said more than twice, That breathing less air beats breathing you" ----- OUCH!!!!!As to say that she??? was even worse than the feeling of suffocation.

"Good judgement.......worth it's weight in gold" Shows that
the learnt the value and process of keeping quiet and/or choosing the right times to speak up when pissed off. Then finishes off again with another hectic insult----"That seeing you is like pulling teeth, and hearing your voice is like chewing tin foil"!!!!!

"High fives to a better judgement
By saying less today I will gain more
Low two's to you my fickle friend
Who brought the art of silent war"

And I guess to finish off his own self satisfaction/gratification of knowing that making the right decision (whether it initially hurts you or someone else)in the long term will turn out for the best for u.
