What would you use as a response ? Is humankind inherently kind or cruel ?

The conventional explanation is that people are able to do terrible things to other people only after having dehumanized them. In the case of the Holocaust, for example, Germans were willing to exterminate millions of Jews in part because Nazi ideology taught them to think of Jews as subhuman, as objects without the right to freedom, dignity, or even life itself.

it's called a epic poem i believe, hope this ☺

greet them:

buenas noches.

that is considered night time which is when "good night" is used.
