Suggest a TV Show with A Likeable Main Character Doing Bad Things

I'm looking for TV series with a main character who is likable but is doing violent or immoral things. They can be an overall good person or not. I prefer series that are complete and limited run. Nothing episodic. Some examples of what I like are Mr. Robot, Daredevil, Barry, Archer, Supernatural, etc. I especially like intelligent, antisocial, and grumpy main characters.

I see Breaking Bad recommended a lot, but Walter White doesn't seem likable, so I'm not sure I'll get into it as much.
