Is that the old Punisher logo or the new one?

My knowledge of 40k lore is limited, perhaps someone can fill in a bit. I know these dudes are both generic archetypes from the game, and are zealous supporters of their God-Emperor.

Is there a bit more info anyone knows that would add some layers of understanding to the interactions here, particularly at the end?

Basically the Emperor, a human who was effectively immortal due to his psychic power constantly regenerating his cells, began to be considered a god because of a combination of lies from the chaos lords and because some of his followers simply couldn't reconcile his existence without him being divine. He constantly fought against it, telling them he was not a god.

Due to the chaos lords interference, a cult formed that would accept him as nothing less than a God. They fought a huge war and the Emperor was triumphant, but was so wounded that he was going to die. Unfortunately, his mind and psychic powers control FTL travel and some other stuff, so he had his people modify a 'throne' he had been creating to help him control the daily duties his mind performed easier. The modifications would keep his mind functional even as his body rotted and decayed.

The great irony is that he began to be worshiped anyway and his skull is the symbol of the imperium because it shows his willingness to sacrifice himself to 'protect' Mankind.

The effect of trillions of human beings expressing a deep faith in His divinity has massively empowered the Emperor's mind and soul. Whatever He may have been before the Horus Heresy, the Emperor now truly is a God within the Warp, equal in power to any one of the four major Chaos Gods, and very likely as powerful as all four of them combined, as He has become perhaps the strongest spiritual force for Order in the Milky Way Galaxy. His mind must claim the life energies of 1,000 human psychics a day to empower FTL and other functions of the imperium.
