Has Chaos already won? My faith in the Imperium is weakened

[Iron Lord]

3. Psykers Emperor said they were bad. Council of Nikea (sp?) Basically saw the Imperium and the Space Wolves black ball the Thousand Sons. When Magnus used his psychic abilities to try and help, he was declared a heretic and the Wolves went with the Emperor's blessing to kick there arses and bring Magnus back for disciplinary action. Now a days space marine chapters have librarians all the time, even the Wolves have psykers and while psykers may not be really like or trusted they do exist and their use is condoned and accepted. Heck the inquisition use them, there's a whole chapter of psychic marines (Grey Knights)

 

The Wolves were still using their psykers "rune priests" after Nikea. And the Dark Angels were using Librarians immediately before the Heresy.
