Já foi bem estabelecido que a Finch construiu a Máquina para proteger as pessoas, e ele tem uma política rígida de não matar. Ele fica arrasado com o fato de que sua criação estava pedindo à equipe que matasse o senador.
Esta citação de POIO wikia :
Finch is shocked by the implications of the Machine asking them to commit murder and Shaw questions if its possible. Finch admits that it is but it would take the Machine predicting that taking a life would save many more though how many Finch is unsure of. The three argue the moral implications of what they are being told to do with Finch attempting to convince and even bribe McCourt into not letting the Samaritan legislation through. However, McCourt refuses to relent and Reese is persistent in their need to kill him as the authorities surround the house. Finch tells Reese that their mission has always been to save lives and if the Machine is asking differently of them than he can no longer do its work.
