As you play through The Outer Worlds Doom That Came To Roseway quest, you will meet Cassandra O'Malley. She has gotten herself trapped in a cell, and needs your help to get out. But should you kill her or set her free?
The Outer Worlds - Should You Free Or Kill Cassandra O'Malley?
When you find Cassandra, you can talk to her and discover she is the person who led the raid on the secret lab. She is not very apologetic about killing people there, but she also doesn't pose a direct threat to you, so there is no need to kill her straight away. You do need to decide what to do because she has Anton's Research, which you need to either return to Anton or sell to Gladys on the Groundbreaker.
You can also be pretty sure that Cassandra being free will lead to more violence and death. There is a good solution, however. If your persuade skill is high enough, you can convince Cassandra to cease hostilities with the guards. Return to the entrance to the covert lab, and you can convince the guards to stop fighting with the raiders. Just tell the leader of the guards that you think he has more to offer than dying in some nameless lab.
The security guards will agree to leave and will give you the key to open all the doors in the lab, and this will allow you to free Cassandra. If you choose to kill Cassandra, you will get some XP for killing an enemy, and Anton's research. If you release her, you can get some Bits, and tell her she has to give you Anton's research anyway.
If you let Cassandra live, you will also have access to the Journey Into Smoke mission from Lillian, who you will meet outside the exit of the secret lab when you leave. It is better to let her live, just from an experience point of view.
If you lack the dialogue skills to talk both sides down but need to get the security key, you will need to follow this guide to find a terminal and print one out.
