They don't know what they did.

 For some all their flesh desires is a proximity to whiteness. Truly, at any cost and ultimately all that will ever occur is that they will be underlings on their own life. Truly I wonder if Mariam even understands what she did wrong and she almost died by her lust to be close to whiteness. Ironically saved from death by a black person. I am okay now but they don't know what they did
