Please people for the last time it was not blood magic! That would imply some sort of ritual or psychic power however it didn't. The Grey Knights made the necessary call... Put it this way the Grey Knights did the Sisters a favour, i'm sure they would rather die than turn heretic and if the GK didn't attack them they definitely would have become heretic. I mean no one was safe from the corrupting power of the bloodtide...
