Without trying to give you any hints...
Set them free, it'll be better for you as you get further into the game. I know in the short term you gain more, but for the long term it will work to your advantage. (Trust me on this)
kill them
Big Sisters are Little sisters who have been converted in a Big Daddy sort of way. You battle multiple Big Sisters throughout the game, as you kill more Big Daddies, and collect more Little Sisters.
Yes he does die, but its not really atlas, its fontaine and a bunch of little sisters kill him
You need to kill the big daddies, but you can choose to free the little sisters or convert them to pure Adam. There is no alternative method for Adam acquisition. This is obviously where you collect the majority of the Adam in the game but there are other places for small amounts. I am not far but I know befor you enter sirens alley there is Adam in the shape of coral in the water. I think 3 of them for a small total of 30.
kill her
In order to save the Little Sisters, you must first kill the Big Daddy protecting them. Any gun fire or plasmid action directed towards a Big Daddy or Little Sister will cause the Big Daddy to become hostile towards you. Once he is defeated, approach the Little Sister. You will now have to option to harvest or save the girl.
There is no sequence where your character kills a little sister at the end of bioshock. during the story you get the option to "harvest" or "save" the little sisters found throughout the game. "Harvesting" a little sister forcibly removes the "ADAM slug" from there body and you get a higher "ADAM" payout but the little sister does not survive the process. While "Saving" a little sister cleanses the "ADAM" from there system, but with a lower "ADAM" payout. It is up to the player to decide what path to take.
Al Capone tried to kill some of his sisters but not his brother
didn't they all get killed? And the better question is, did you kill them?
kill e'm
Because he likes to kill his sisters.
