Some don't see the way they are being used for evil.
We have posters that think "I" am evil because I don't think the porn they found at DW's means he is guilty.
I think that evil is trying to get people to disregard 'thinking for themselves'. Mob mentality. The crowd in the Coliseum turning 'thumbs down'. The crowd in the coliseum thirsty to see the Lions devour the Christians.
They have been given the 'lamb' , the 'innocent' as a sacrifice. Now the devil is having fun with the witchhunt. Meanwhile the devil is keeping the true evil protected.
