Sinners have to burn in hell and this is an ancient as the world truth. The only caveat is that this hell is here on Earth, and burn the person starts during his lifetime. Beating demons is Providence's favorite joke. If life hits a man and hurts him, it just wants to beat the sins out of him.
Very often the man himself does not know and does not see his sins. He may be full of pride, vanity, complacency, greed, stupidity, or be a traitor. It is very difficult for a person to see sin inside himself on his own. If pride can still be recognized in oneself, then greed is more difficult to recognize, and stupidity is almost impossible to recognize. That's what pain is for. When a person is beaten, it means that life expels sins from him.
The classic scheme of exorcising demons is occupational therapy and beating the possessed with sins. The demons of pride and greed demons are lured to hell via "nadrezanno Apple" or "cheese in a mousetrap", so to speak, enter him into temptation, offer him something shiny that he is ready to give his soul (as a rule, is a fiction and deception). Then the Demon put on the yoke and begin to beat him up and piss, forcing to work till the 7th of sweat from morning till night. Under the influence of such occupational therapy, the Demons of sin often leave their master, so as not to be subjected to such bullying, and the person finds freedom.
Such occupational therapy and beating are very useful from all sides:
First, demons are very strong, and if harnessed and forced to plow, they will work very hard and bring great benefit.
Secondly, all other people, seeing such a beating sinners, imbued with fear of sin, so as not to be in such an unpleasant situation.
Third, it is possible to torture a Demon so that he will be frightened and run away, freeing the human soul from its painful presence.
My reader may think that I am telling something from the realm of myths. But no. I tell how in real life greedy, stupid, arrogant people are usually punished by other people. Their "check for lice", tempting bait, and those who gets the hook, take in slavery, heavily exploited and bullied.
