10 Most Evil Choices In Video Games

Returning to the haunting ocean city of Rapture once more, Bioshock 2 tells its story from a very different perspective. You play as an Alpha Series Big Daddy named Delta.

As a little history to this former paradise and its goings-on, the Big Daddies are biologically-enhanced humans exposed to a method named 'splicing'. This is when the chemical named ADAM is consumed to rewrite genetic material, or in other words, change their bodies.

The sole purpose of a Big Daddy is to protect their Little Sister. Each Big Daddy has their own, and Delta's is named Eleanor. The events of Bioshock 2 centre around Delta's attempts to find Eleanor, who was kidnapped by Sofia Lamb a decade before the game's plot.

As with many video games, there is a skill tree, and the quickest way of upgrading Delta's abilities is with ADAM. You can encounter many other Big Daddies throughout the game, and should you kill them, you are presented with a choice: you can either adopt their Little Sister or absorb them for their rich ADAM supply.

Don't let their odd appearance fool you; these Little Sisters are just genetically-modified children. Absorbing them for their ADAM kills them, meaning you are killing little girls to improve your abilities. It doesn't get much more heartless than that.
