If we are considering real people, then I can say my parents are role models. I know this sounds cliche, but it's true. If they know the twists and turns in life, then it's a good thing to listen to them.
But if we are talking about fictional characters, I'd say Vriska from Homestuck. She may be a huge bitch, but atleast she has the principle to do what's right. I wouldn't say she's my role model, but I do admire her because of it.
