For me the eighth sin is, “PREJUDICE”. It is a baseless and usually negative attitude toward members of a group.
When God created us I wonder if He thought that His creation will not get along because we are different. By this I mean not all of us speak the same language or practice the same religion or have the same skin color.
I remember I went to a store in a city where they will not speak to you if you spoke English, even though I was a customer and was there to spend my money and they were employed to make sure that the customers were treated with respect.
I was discriminated because I did not know their language, this is prejudice #1.
Then there is the issue of religion, what difference does it make if my religion is not the same. If I practice a certain religion, I am considered a terrorist, therefore they will have nothing to do with me.
Number 3 is color of my skin, why should it be an issue, but it is, there are known facts where if your skin color is different from the natives they wont rent their house or apartment.
I think eighth sin , “Prejudice”, is just as evil as the other seven sins!
