The evil injustice I am bringing to your attention is when people capture and exploit, even kill the vulnerable for their own deluded benefit. And if they do this even to their own people, even their own children, it is all the worse!
I hope you will agree this is wrong. If you do not agree, then you will have to await God's decision on the matter at His judgment seat. Whether you BELIEVE that judgment will happen or not does not matter, you will find out, and it will be too late.
If you are like most people and recognize this kind of exploitation of the vulnerable as unjust, wrong and evil, then it behooves you to open your eyes and see what is going on around you!
