Maybe "Only Death is Real" is just tossed about because it's a badass-sounding slogan from a legendary band; it's exclusive, lethal, definite, and pure. If so, stop me here.
I suspect that the slogan began as that, but it seems certain Hessians have integrated it as a motto for the culture.
If it is meant as an actual ontological statement, then how is it valid? Everyone will die, so only death is real? Is only death real because everyone experiences it, in which case only birth would also be real?
For those of you who have experienced a dead body (no necro jokes!), I trust you'll agree that the 'death'ness was real, intense, illuminating, and struck you with a certain awe. However, it wasn't real at the expense of all other things.
A more accurate and useful phrase might be, "Death Alone is Certain" (which Stephen Bachelor pulled from Buddhism, I think). For me, that is more empowering as a goad to action.
How do YOU interpret/use "Only Death is Real"?
