For any statistic junkies out there like me, check out this for the "Fate vs Free Will" debate - every single mention of "constant", "destiny", "fate" and "we have to go back" VS every mention of "choice", "choose, "don't tell me what I can't do" and "variable".
I toyed with whether to do a full-scale every single mention of the words or a contextual count of the mentions - I've gone with contextual, so you will see Randy's mocking "You think it's your destiny?" or Christian's "Don't choose. Don't decide." count as negatives as they are anti-statements, and you also won't see Locke's rants count towards 35 "destiny"s - one line, one count.
Anyway, have fun!
S1E4 - Locke - Why? It was his destiny.
S1E4 - Locke - This is destiny. This is destiny. This is my destiny.
S1E14 - Michael - This us taking control of our destiny.
S1E24 - Locke - It's destiny.
S1E16 - Christian - It's fate.
S1E21 - Haddad - Perhaps it is fate.
S1E21 - Essam - Haddad was right, it was fate that brought us back together.
S1E24 - Locke - We'll let fate decide.
S1E24 - Sun - Fate.

Free Will (25)
S1E1 - Jack - So I just made a choice.
S1E5 - Unnamed Bully - It's your choice man, walk away now and you won't get your ass kicked.
S1E6 - Locke - Give it up now at least it will be your choice.
S1E7 - Priest - Well, we all have our temptations, but giving in to them, that's your choice.
S1E7 - Charlie - Well, then, I've made my choice.
S1E7 - Locke - Having choices, making decisions based on more than instinct, is the only thing that separates you from him [a boar].
S1E7 - Charlie - I've made my choice.
S1E8 - Jack - This was Sawyer's choice.
S1E16 - Duckett - Only two choices, shrimp in mild sauce, shrimp in hot sauce.

Anti-We Have To Go Back (2)
S1E13 - Boone - We never go back.
S1E20 - Shannon - I don't want to go back.
So, there you have it. It would appear, for Season 1 at least, there is a dead-even tie between Destiny and Free Will. Spooky! I think Sayid says it best:
S1E20 - Sayid - Maybe we should go back?
