Just going to throw this out there as a matter of debate, in the Grey Knights book "the Emperor's gift" the Inquisitor from Fenris has a follower/lover who is a reformed Chaos Cultist. And I mean that he had Chaos Symbols cut into his skin still, so he was probably the kind that babled incoherant sentances trying to summon greater deamons.

Also, doesn't faith in the Emperor have a purifying effect upon the soul in opposition to the croupting effect that Chaos worship has. If so, could this be used as a methord to purify someone?
