The C's have mentioned that "doing nothing in the face of evil is the same as committing evil" or something along those lines, can't seem to find the direct quote but I know its in there. We also know that 4th Density STO/STS are at war with one another, and they are in essence, "polarized souls". They have talked about the bible promoting pacifism and the dangers of that.
Could be wrong, but I don't think the C's said that. There is this quote that does the rounds every now and then. Some say it was Edmund Bourke who originally said it:
The only thing necessary for the triumph of evil is for good men to do nothing.
Some say that Bourke didn't say that at all and that the original thought behind the quote come from philosopher John Stuart Mill:
Let not any one pacify his conscience by the delusion that he can do no harm if he takes no part, and forms no opinion. Bad men need nothing more to compass their ends, than that good men should look on and do nothing. He is not a good man who, without a protest, allows wrong to be committed in his name, and with the means which he helps to supply, because he will not trouble himself to use his mind on the subject.
