"Do good things, good things happen. Do bad things, bad things will hunt you back."
Do you ever had your phone stolen?
Your car broken?
Your girlfriends stolen and your heart broken?
Do you ask God why you should through all this things?
But do you ever think, you DESERVE that?

And now.
I repeat again.
"Do good things, good things happen. Do bad things, bad things will hunt you back."
You are bad guy, you get something you didn't deserve, than it's gone, while affect your life.
Well, that's how Karma work.

I can't say that I believe in Karma, because I really can't.
'Karma' is an Indian religious concept in contradistinction to 'faith' espoused by Abragamic religions (Judaism, Christianity, and Islam) which view all human dramas as the will of God as opposed to present - and past - life actions. In theistic schools of Hinduism, humans have free will to choose good or evil and suffer the consequences, which require the will of God to implement karma's consequences, unlike Buddhism or Jainism which do not accord any role to a supreme God or gods. In Indian beliefs, the karmic effects of all deeds are viewed as actively shaping past, present, and future experiences. (Wikipedia)
It's Hindu religious concept, that's why I can't believe it.
But some of the concept can be taken for make you a better person.
