Do you believe in karma?

I believe in karma, it's simple enough to understand that if you do good deeds; then you'll get a taste of that later on in life. If you do bad things, then you'll just end up like a lot of today's statistics. Although everything won't come good because you do good things, and vice versa; you still have to credit the things that go according to plan as well. Just my personal thought on karma; because if you give someone your ass to kiss, you can expect that shit in return sooner or later.
