Big Sisters mentally unstable and extremely violent ????? Edit
In the Big Sisters section it states that the Big Sisters are mentally unstable and extremely violent. I have seen no evidence of this in game. I have not seen them violently rampaging and just killing at random. They might be very single minded in protecting Little Sisters or trying to destroy Delta. I think that they are extremely powerful rather than extremely violent. They stalk and occasionally attack Delta throughout BioShock 2 under orders from Sophia Lamb, (not the actions of a crazy unstable, violent being). When fighting them a Big Sister might go into a hyper fighting mode, but I would not call it a 'rage' as the Big Sisters are very powerful, clever and cunning when fighting. A rage usually means lack of self control or uncontrolled violence. Is there any real evidence that they really are mentally unstable and extremely violent ???
The proof is in the audio diary: Growing Up, by Gilbert Alexander where he states that they had become feral growing up in Rapture's enviroment. In the audio diary Big Sister it's revealed that they were made less aggressive and more controllable by mental conditioning. Night at the Kashmir (talk) 21:44, May 12, 2014 (UTC)
Thanks for the explanation.
