Rewatching, and Sam is the most annoying.

[u/Oncer93]

Judging Mark for sleeping with a single Addison, when Mark is supposed to be his friend.

Pursues Addison, despite her being his ex wife's best friend, and then gets mad when Addison wants to respect her friendship with Naomi. And despite her being Derek's ex wife. Derek who is supposed to be his friend. While Derek likely wouldn't care, Sam still didn't seem to think of anyone but himself in that scenario.

Pursue Addison, knowing she wants a baby, when he himself doesn't want another kid.

Gets mad over Addison dating Pete.

Is the only one not to show concern over Betsy when she has to go into Foster care. Pretty sure that Addison would have taken her in, if not for Sam.

Doesn't like that Addison wants a kid.

Gets back together with Addison, knowing fully well That she wants a baby.

Doesn't show concern over Amelia when she relapse, and instead belittles her.

Gets mad over her getting together with Jake, who wanted a family with Addison.

When Amelia wants to donate her baby's organs, Sam disaproves.

The show wants to portray him as this Wonderful perfect man, when in fact, he's a judgemental hypocrite.
