They just teach them how to do it right.
They teach them nowadays, before it was basically DO WHATEVER YOU WANT COS' ELDAR LIFE IS FREE.
Yeah. I don't see your point here. I'm talking about nowadays. They didn't seem to have trouble with Daemons before Slaanesh showed up either, though, so...*shrug*
Less time to fuck up if there are only like five seconds after your birth when you can fuck up before brainwashing.
Teaching how to not summon Daemons while manipulating wraithbone=brainwashing. Okay. The 'less time to fuck up' and 'more time being taught' was kinda my point.
Good for them, that they need some constant reminders.
Yeah. The constant reminders means they don't have to exterminatus Craftworlds. It's pretty helpful.
Eh, they might not be that great again if it takes them hundreds of years to grasp such basic concept as "NOT FUCKING AN CHAOS GOD INTO EXISTENCE".
What's fucking got to do with anything? I mean, yeah, it takes a while to imprint sexual and emotional repression into people, what's your point?
That explains why they do that, though it would be hard to forget FUCKING AN CHAOS GOD INTO EXISTENCE, AND BASICALLY PSYCHIC GENOCIDE OF THEIR OWN RACE.
Well, if I remember right, the Craftworld Eldar didn't do that, in any case. That's why they survived. They had to have discipline on the trading vessels, so they didn't all die from being too successful at life. As compared to physical genocide of all other races. Okay. I mean, there's also the whole Harlequin deal where they hold plays to remind everyone not to be too happy because eitherwise
the bogeymanSlaanesh will get you.
The all-natural psykers was the reason they fucked up in first place.
This is kinda like blaming the dog for being four-legged, which is why it couldn't hold that assault rifle. Like, no shit, but what difference does it make here? Also, see below about 'entire galaxy's worth'.
The thing is that Emperor might actually answer those prayers (Sisters of Battle cause miracles on daily basis), and so might Chaos Gods, so "wrong cantations and rituals" might mean "OPENING A FUCKING GATE TO WARP IN MIDDLE OF TERRA" or actually mentioned "FUCKING AN CHAOS GOD INTO EXISTENCE", you don't need to be psyker for psychic entities to act... and Cult Mechanicus cantations are basically maintenance protocols so if you screw up you might end up exploding the entire planet with acient toaster... or, if the thing they're talking to is advanced enough to be called an "Machine Spirit", screwing up might cause it to go on murderous rampage.
DUDEMAN. Capital letters are UNNECESSARY. As you can see, they DON'T REALLY CONTRIBUTE to the discussion, and it makes me think that you might be a bit OVERZEALOUS IN YOUR HATRED ON AN ONLINE FORUM THREAD MEANT FOR THE DISCUSSION OF ALL THINGS 40K AND NOT JUST MINDLESS ADORATION OF THE EMPEROR.
Seriously, Kot. Calm down. I get that you love the Imperium. They are not the end-all be-all 'best-guys' (there are no good guys) in 40k.
Furthermore, Sisters of Battle have a shitton of different prayers. Emps can hear you pray regardless of whether you have proper diction. If the Chaos Gods have taken an interest in you, same applies. Sisters of Battle have an exceptional level of faith not present in the average Imperial citizen, who's just trying to get through the day without dying of poisonous smog in the mid-levels of their Hive Cities. It took about literally a galaxy's worth of the strongest large-number psykers in existence experiencing the limits of their heightened emotional capacities to summon Slaanesh, and she still got beaten on by Khorne afterwards. If you're not on Terra, you're not going to open a Warp Gate to Terra by pronouncing a few syllables. There's a reason sacrifices and shit are needed.
These are all reasons to 'teach them how to do it correctly', not 'slaughter the lot of them, obviously they're too stupid to be worth anything other than rations'.
