People Often Use Calling Other Humans "Animals" as a Very Insulting Slur, Yet Those Same People Do Often Site the Brutality of Other Animals, as an Excuse for That of Humans Towards Other Species.

The origin of the word humane is human. Personally, I find humans no more "humane : (marked by compassion, sympathy, or consideration for humans or animals) ", in general, than that of the supposedly lower species.
