Of course, I agree with this. It's what I base most of my life on. In the grand scheme of things, I do believe in karma and universal energy (I'm honestly terrified of thoughts being manifested - esp. when concerning family). That being said, I believe that people feel the energy of others, and negative people's actions will, eventually, come back to them and blow up in their faces.

And if it doesn't, it doesn't.

There's no use dwelling on the negative people in the world unless you're directly associated with them and are trying to rid them from your life. Eventually, they will be alone in life and reflect on all the misdeeds they have done in their life.

As for the good and kind, we can rest soundly, reflecting on the positive we put out in the world.

Do unto others, no matter the outcome.
