You can be quilty and ignorant at the same time.
To be ignorant (for example do n ot know that something is not allowed in the natianal law) does not make you less quilty.
I agree with most that it is not a big consipracy there. I do think they believe that they are doing actually good, and believe what they teach themselves.
Now what are they quilty of? Giving wrong information? Giving a wrong interpretation of the a story book? Hard to prove....
Lying? Probably not. (what is the definition of a lie?) Withholding information: yes, but that is no crime.
Torring families apart. It is the families that do it (they do not even teach it actually)
The blood policy. Causing dead (not murder of course)? Yes maybe. But here again the people themselves do it. Hard to say if some other teachings are actually benificial for people...
