Man... the start of the Horus heresy series was the 40k I always wanted. Crusading through a hostile galaxy to spread the light of science and civilization.
In my mind the traitors will always be the good guys. Not the corrupted leaders, but the marines themselves, they were always on the right side of it.
The government is corrupt
and we're all on so many drugs with the radio on and the curtains drawn.
We're trapped in the belly of this horrible machine
and the machine is bleeding to death.
The sun has fallen down
and the billboards are all leering
and the flags are all dead
at the top of their poles.
