 Cole is finally able to track down John , but learns that John is neither from the FBI nor Moya 's husband , but instead an undercover NSA agent who assisted in the creation of the Ray Sphere . John explains that the Ray Sphere consumes the bio @-@ energy from those around it and transfers that power to the person holding it , granting them superpowers at the cost of thousands of lives . John urges Cole to help him find and destroy it . Alden goes on a killing spree while heading into the Historic District . After a long battle , Alden is defeated and jumps off the bridge . During the battle , Alden destroys huge sections of the bridge . Cut off from the Warren , Cole goes ahead into the Historic District . As they search for the Ray Sphere , Cole discovers that Kessler has kidnapped Trish along with six other doctors , and forces Cole to choose between saving her or the other doctors . Regardless of the player 's choice , Kessler has arranged for Trish to fall to her death , but is briefly revived by Cole . If the player has good Karma , Trish will be proud of Cole and profess her love , while if the player has bad Karma , she will curse his name with her dying breath . After mourning for her loss , Cole works with John to recover the Ray Sphere ; the player can then opt to either destroy it or use it to further enhance Cole 's powers ( which also gives him red and black electricity ) , but either option causes the Ray Sphere to malfunction , disintegrating John . Once the player chooses their side , they cannot change their Karma level , either being Hero rank ( Good Karma ) or Infamous ( Bad Karma ) .
