For those not into 40k, the Space Marine in the meme is Erebus and he's commonly considered one of the biggest pieces of shit in that setting.
A setting where planets of billions of people are pretty commonly glassed from orbit "just in case" and he makes the people giving those orders look good and justified.
Sabotaged peaceful first contact between the Imperium and another independent far more advanced and enlightened human civilization, all in a bid to corrupt the Emperor's favorite son and spread his literal devil worshiping religion......all while being extremely smug and condescending about it
Basically killed the 40K universe's version of The Culture for evil shits and giggles
The character is the definition of out of pocket
Don't let unironical fans of senator Armstrong find out about that guy.
This is a canonical Erebus quote as far as I'm concerned.
