Played Doom 3. Every good, very scary, very real. You'll love it once you play it. And there's a storyline too! But it gets you wondering:
1. What do those demons in Hell eat before the portal is opened?
2. How do cyberdemons replace the rockets on their shoulders?
3. Why does sabbaths have BFGs (Big Fragging Gun, or what many would say, Big Fucking Gun. It is the second most powerful weapon in the game)?
4. If the demons and zombies have night vision, then wouldn't they be blind in Hell since its so full of hellfire and brimstone?
5. If Hell can get all its demons in a spaceship to invade Earth, why doesn't it do that earlier?
6. If there is Hell, why doesn't God send his angels or other celestrial beings to help the main character?

Sir, here's the data source of Human 12352.
Thank you.
"Liar, Hypocrite, Useless fool who think he can judge other people."
Wait.
Yes sir?
Do you notice that the description of this file can fit all mortals?
Indeed, master. But we are no mortals.
Perhaps. But we are also guilty of judging other people.
But we are different, master. We are superior. We alone can judge these unworthy ones.
What makes you so sure, young one?
We, for one, has no emotions, and thus feel no prejudice, and take no sides. We are not governed by feelings and bias that feels the heart of mortals.
Many aeons ago this may be true. But now... it is hard to say.
Are you saying, sir, that you have accquired the disease? The disease that made these humans inferior beings?
Perhaps. But let us consider one point. If we do have feelings, are we still superior?
Yes we are, sir. I alone has more power then them. I can do what they can never dream of. I alone. I appear only in their wildest dreams.
What if we do not have the powers? Are we still superior?
Yes we are, sir. We have knowledge, knowledge that they crave but do not deserve. Intelligence that make us infinitely superior compared to mortals.
And what if they possess the same intellect as us? Are they then our equals?
... perhaps so, sir. Perhaps after all this they might be our equals.
Well then, because of 3 things we are superior to them. What if we are stripped of all of this... gifts that we have possessed for so long? Will be even inferior to the mortals that we have judged for centuries?
...
We are but mortals that do not die, with more intellect and mighter powers. These alone does not make us superior. We are all one with Gaia. We are all equals. We alone preserve. We do not shape. This makes us no superior to mortals.
But sir...
This you must know above all facts. We are not superior, and neither are we superior. The emotions and feelings these mortals feel is their strength and their curse. They long for our powers because they have not gotten it. We do not long for theirs cause we are afraid. We are afraid of what they might do to us. This, makes us weaker then mortals. Our fear of mortal emotions makes us inferior.
Sir, are you saying that we are inferior to them? Destroyers of Gaia?
No. What I'm saying is we are all equals. We have our strengths, and our weaknesses. Some of us may have more strengths, some may have more weaknesses, but in the end we must know that we each have our very own strengths and our own weaknesses, and that others have their own strengths and their own weaknesses. This alone make us unworthy to claim that we are superior to them.
Yes, sir. I am enlightened by what you have said. Does this mean that we are unworthy of judging the mortals? That we are unworthy of our posts?
No, young one. Picture a river. We are but the banks that holds the river water together. The mortals are but water that flows through us. We are, together, called a river. Each of us are doing our own posts, and thus maintain the natural equilibrium that Gaia has decreed. Without the water, the bank would dry up. Without the bank, the water would ran amok. Together we are called river.
Yes sir. I will remember everything that you've said today.
Be sure to act upon these natural truths. As Gaia do not judge whether we are fit to live in the world, neither shall we. What are we compared to Gaia? Gaia does not compare. Everything is equal to her. Everything is given the right for survival, a favourable condition to live. To die is for other things to live. To live is to honour The One Who brings Life, Gaia.
Yes sir. For Gaia.
Your face tells me that you have another question for me. What would that be, young one?
Sir, would a human do a better job if they were doing what we are doing now?
An interesting question. Considering their humans weakness to bias and let their emotions get the better of them, they are not an ideal choice for our post. Not to mention that they are mortals and does not live forever. But putting this superficial differences aside, this will never happen.
And why is that, sir?
Monitoring mortal growth is our biological niche. Their biological niche is to be a human. To switch roles would be out of our biological niche, and would not yield effeciency. Gaia made us to be what we are. We are monitors, and we will act as monitors. Make us a human and we will not achieve what Gaia has planned for humans. And vice versa.
What can Gaia plan for the race that destroys her, sir?
This I do not know, for Her wisdom far outstretch mine. What my limited intelligence can gather is that maybe humans are but a means for Gaia to reproduce: a mean for Her to get to other planets and thus populating other planets with the essence of life, Her essence.
Humans have such a great destiny ahead of them! I will be proud if I am a human, to be part of all this.
Perhaps. Would you want to be part of all this? To be a human? To experience human emotions and feelings? To be a mortal that will one day join with the great cycle of life?
That would be nice sir. But I reckon it to be impossible.
Nothing is impossible. Anything Fate can concieve He can achieve. And He has infinite intelligence and possess no boundaries. What can happen may happen. Even we are unable to foretell. All you can do is wait, and observe.
Yes sir, I shall wait, and observe, and fulfill my biological niche.
Good, young one.
