As explained thru Hindu comic books
Tony Soprano was TV's first anti-hero, but the show still has a hero. It's his wife, Carmela. In a very Gita or Kannagi sense, she's a dharmic hero. She does her duty. She's a good wife to a bad man. She's the hero to his anti-hero.
Dharma is, inadequately explained, doing your duty. Fulfilling your societal role. Following the morality specific to you. The god Krishna (in blue) gives an entire sermon on this in the Bhagavad Gita.
Here the warrior Arjuna is about to slaughter his cousins when he just drops his bow in the middle of the battle-field, bereft. "How can I kill my fam?" he says. "Bro," says Krishna, "you're part of a bigger plan."
The Gita is like the Hindu Sermon on the Mount, an isolated passage used to encapsulate a whole philosophy, in many ways the same philosophy underpinning Buddhism. As much as it seems to underpin caste and class bullshit as well, there's a deeper meaning to it, about meaning itself.
The Gita offers a very different conception of good vs. evil, namely that the very distinction is a misconception. All things are one. According to Krishna, an 'even-minded' person can feel this and just acts in accordance to dharma. You don't crave a particular outcome, but just do what you do as a part of cosmic order, on a cosmic scale which, by definition, the human mind cannot understand.
To Krishna even an uneven-minded person can still approach this vibe through worship (through him) which is the access given to Arjuna. Krishna reveals his true form and blows Arjuna's mind.
