Thought does this. Just look around. It's men vs women, blacks vs whites, this religion vs other religion, this nationality vs other nationality, my team vs your team, me against you. Thought in the fragmentary perception makes up divisions on every level and from those divisions conflict springs up.
Thought is the response of memory. And memory isn't anything noble or holy. There is nothing holy in the thought 'I AM'. It is NOT 'God' in me. It is just conditioning of the brain. As the computer is programmed, also the brain is programmed from a very young age. Then it repeats: 'I am a Brit' or 'I am an Indian'.
For a hypnotized desensitized person killing, plundering and raping may not pose a problem.
