What is humanity?

I saw it through 3 very different movies at 3 different occasions.

One made me decide I will not support diamonds, adding to the fact that I never fancied jewelries.

Another made me smiled yet got me thinking...

And another made me cry hard in the cinema..because I understood it well.

So what is humanity? What made us humans?
