I'm sure it was the educators who came up with this - not the students. As we all know, the teachers unions have turned most teachers into liberal schills. The solution is to get unions out of government.
You referred to the evil of humanity. That would be humanity's evil. It's possessive, not plural, since humanity already encompasses everyone. Unless, as noted by mrbill, you referred to the study of humanities, and the evils of such study. You're welcome.
Then you made a stretch drawing that parallel between humanity's evil and God's wrath. That same deity is said to have made Stalin and Mao in its image. If you don't mind asking, are you in fact trying to build a cast iron case FOR honoring great mass murderers?
Probably. But would such an idea even be conceivable 20 years ago? What line of reasoning/conditioning would allow such a display to be considered, "OK" or even possibly OK, now?
