The systematic destruction that is wrought around by killing human beings due to discrimination based on race or ethnicity or even religious faith is known as genocide.
In the past century, humans have been subject to mass genocides and it has not just been bloody but also shameful on the part of us humans to have stood by and let this happen.
The holocaust is ofcourse the biggest example of the genocide, but there have been other like the one at Rwanda and then later on at Darfur that have almost proven that human are no better than animal and animals might actually be better than us when it comes to killing their own kind.
