she thinks she can have everything she wants, do whatever she wants and people belongs to her!

no she doesn't. Brooke gives so much to the people around her.

yeah, Brooke is a great friend to everyone she knows, if she was selfish, why would she go back to one tree hill for peyton?

^^^She didn't come back for Peyton she came back to start a family!

exactly!! peyton was only her excuse but not the real reason

wanting a baby isn't selfish she wants to start a family of her own and that is not selfith. lucas is selfish cause he kissed peyton but he got engaged to Lindsey that night he didn't even think about have peyton felt

cheating on brook in s1 was selfish. he didn't take into account what it would do to brooke or breyton's friendship. leaving peyton in l.a. cause she wasn't ready to get married was also selfish. he wanted all or nothing. kissing peyton the same night he proposed to lindsey was also selfish. Luke's very giving, but he's rarely willing to put his heart on the line (since s1 when he opened his heart to peyton and got shot down BIG time at first in 1.07) so he hides in relationships not taking into account what it'll do to the girls he's hiding with (brooke, lindsey, anna) when they realize it. He gave hales a hard time cause she was dating nate (who was clearly changing for the better) cause he was too proud to admit (at first) that he just missed her.
Not to take away from what he has done as a selfLESS character, cause he also tops everyone for most selfless character in other ways, but he can also be very selfish (when it comes to relationships). The guy's a conundrum :P

Haley is so selfless, and Brooke is pretty selfless too... and how could Nathan be selfish? He does so much for his wife and son, just like Haley does for Nathan and Jamie and her friends... love her!
I think Peyton can be selfish at times, but she is not a selfish person.
I gotta agree with abs.
Lucas is the most selfish person on the show.
He treats girls with disrespect and he does only does what he thinks is best for HIM.
He went after Peyton when he was with Brooke, because he liked Peyton more. SELFISH.
And their is loads more but I'm not going to list them all (especially because abs did, especially about what she said about the naley relationship).

I would say Brooke and Lucas.
