‘Satan’ is nothing but another name for Lucifer, so named by the people of Mesopotamia because it was a comet which destroyed a number of civilisations in it’s path, became the ‘fallen angel’, was known as the feathered serpent, kukulcan and quetzelcohutal in the Americas, gave rise to the world encompassing dragon of the Chinese - and has absolutely no interest in individual human beings or how they behave. He’s the boogie man used to keep children in fear and I would have thought that by now, in the twentyfirst century, with so much else to be genuinely afraid of, (like ebola and islam) this tool would have been laid to rest.
The devil, if he’s anyone, is allah. The rock which fell to earth.
