I ask again: if someone decided, after following the advice you have given to receive spiritual insight, that they were being told by God to commit mass murder how would you convince them they were wrong? Would you even try to convince them they were wrong?
Answer:
If someone says such stupidity I might think he need a shrink ASAP!
I might call 911!
One thing helping to understand Spiritual contact is: it NEVER would have to do anything with other things than, Love, Understanding, Compassion, Solidarity, Unselfishness, Trust, Happiness, Wisdom and Freedom.
Intellect is the one you can blame for instilling such destructive THOUGHTS. Ill intellectual machine.
A mind that "thinks to much" is the one prone to get such monstrous inspiration.
I suppose you get good inspiration most of the time, being a nice lady. When you get good inspiration, listed above, you are "listening" to the Higher Self. It does not matter how you call it.
If someone "listens" to the mean ideas you describe, he is "listening" to the lower self, call it devil, Satan, Chucky, etc.
