Quite a large fraction, I would say. People have been conditioned to think only about themselves, and maybe those closest to them, while closing their eyes to the massive injustice and suffering all around the world. People think it's normal not to have compassion and take responsibility for the injustices of the system in which they take part, especially if that system is coddling them and treating them nicely. That's the Satanic philosophy in practice: me, me, me. We are all responsible for making this world a better place. Thank God something finally seems to be happening in that direction. It took long enough.
For more info on how the world has been Satanized, I recommend Mark Passio's excellent presentation on Satanism and the Dark Occult. You don't have to agree with everything he says. And he consistently fails to touch upon issues of central importance (perhaps you know to what I am referring). But his insight as a former insider is priceless. Well worth the time to listen.
