I once believed in Karma. Not just the philosophy of Karma, but actual Karma. Not so much now. I will continue to do what I believe is right, only because it is right. Not because I expect it to garner any favor in the future.
Similarly, I will not expect those who are bad people, to reap any sort of consequence for their actions.
However, I will hold myself accountable for my actions. I will also hold my friends to the same level of accountability. If you choose to hang out with liars and thieves, then you are choosing not to hang out with me. It is clear cut, no room for ambiguity or shades of grey.
