From what I understand there are certain factors for each character that determine whether they live or die. Loyalty is a factor for most but not necessary for all?
I.E.

Tali's life is totally dependent on whether you upgrade your ships shields. After going through the Omega relay, you get into a fight with some collector ships and Joker eventually has to ram your ship through some space junk. If you have upgraded your shields everything is fine. If you havnt then there is an explosion and she is killed. Im not 100% sure but I dont think loyalty plays a part in this example at all. |
