Humanity lost

A power holding company staff came to my area to disconnect light of people who hasn't paid their electricity bill for the month. On this day, a compound which has six flats no adult was around except for this man who doesn't see clearly and stays alone. The power holding staff got angry with the man(it could be the man was pleading and could possibly say something that might have triggered the staff) and started fighting the man and fell him to the ground . The children in the compound couldn't know what to do and were begging ( this said man is a very kind hearted man and most times clear the electricity bill alone for the flats he shared light with.) Th compound directly opposite the victim compound, they were adults there and saw what was happening but didn't come to the man rescue cos of different tribe I suppose and also the power holding staff is their friend in order to avoid disconnection as often times they dont pay. Luckily, my parents stepped out the house and saw what was happening, decided to step in by rescuing the man as of that time he was pressing this man neck fa, another passerby came and held the staff and told him if you kill this man , you wont be free. That's how it ended. Later in the evening, one of the flat tenant saw this staff on the road and told him the man you beat is kindhearted, if the bill isn't cleared isn't the man's fault as most times he pays everything alone cos he needs the light , that's how the power holding staff guy felt sorry for beating an innocent man.
Where has the humanity in us gone to? If someone is not your tribe, you don't help out, why?Also, why beat someone because you feel you re in power?
God help us all...
