Has anybody noticed that many of the characters have in common bad or estranged relationships with their fathers?

-Ben: blamed by his father for his mother's death; he later kills him
-Locke: bad relationship with father
-Kate: kills her father
-Penny: bad relationship with father
-Sun: bad relationship with father
-Jack: bad relationship with father
-Walt: resents his father
-Sawyer: As a child his father killed his mother & himself (murder-suicide)
-Hurley: Father walked out on him when he was a young boy
-Alex: Strained relationship w/Ben (believed not to be her biological father)
-Claire: not raised by her father, but he later appears mysteriously

Coincidence?
