Why does evil always win?

[Diana]

There really are no mistakes..... I understand it's hard looking at all the suffering going on right now, and all that has happened. Hell, just the other day I had a good cry about it! And that's okay. But it's important to understand that we are all doing our part, the "evil" ones included. Everyone is contributing to this great learning experience.... and I mean everybody!

And by everybody, are you just talking about people?
