Arguably Siddharth’s concept of karma was more of a physics thing than a moral thing. He made friends with the low of society and talked smack about the priestly caste. Believing in rebirth and at the same time not accepting that punishment here is for sins of the last lifetime.

Karma is deed done. If I break your farm you don’t have food. That’s karma. That doesn’t mean I get punished for what I did that doesn’t mean you get a reward to make up for it.
