I′ve just completed Bioshock 2 and I have previously completed the first game.

Since the Little Sisters are a big part of these games I decided to make this poll. What did you decide to do in the game(s)?

For me it was never a choice. I rescued all of them in both games. I neither can nor want to play an evil character, simple as that. I′d rather help those who need it. Besides, you get enough ADAM anyway through gifts. I ended up with filled Plasmid and Tonic slots and I still had 490 ADAM left when Bioshock 2 ended, and something similar when the first game ended.

So, what say you?

There is no reason to go only halfway, you either harvest or rescue them all, and I like to play a good guy so the choice was obvious to me. Besides as you mentioned even if you decide to rescue all of them you are never really lacking ADAM.

Also Bioshock 2 was much better then Bioshock Infinite.

Rescued all of them, harvesting them was never a choice in my eyes. And yea, you are never lacking in ADAM either way.
