All answers based on story and lore (as far as I know it):
…I want her to survive, Im not a CoR fan girl I just want to know whats gone on in the past.
…
She always promised to reveal some secrets but never revealed anything. How often are you willing to listen to promises until you simply don't trust somebody?
Does she really know something? There is not even a slight indication that she might know something.
…
She's on a mission she believes will right a great wrong. She's willing to die in order that the message is heard, she's putting everything she has onto one throw of the dice, this is her "Alamo" moment.…
In the Prism incident she showed that she absolutely can't be trusted to make decisions that might affect thousands, if not millions or billions of people. Rushed decisions made purely based on emotions and what she considers her right - and later (partly) regretting it.
People who think they are right are those who commit the worst crimes. People who think they are right and act without thinking about consequences are those who cause suffering for many.
Are you willing to risk the deaths of innocents, just because a woman thinks she is on a mission?
From my characters point of view she's a traitor and a terrorist. Regardless of what information she claims to have the ends never justify the means and she needs to answer for her crimes. It would be better to take her alive for trial but history has demonstrated the dangers of that. Kill on sight.
That's, sadly from my out of game point of view, the most logical conclusion. If she had some information she could just reveal those informations.
…She is a terrorist and has a lot to answer for, but she definitely seems to have information that neither the Feds or Imps want to get out. Remember the bounty says not to communicate with her.
From my characters point of view, neither the Imps nor the Feds can be trusted and if they want someone dead, its enough reason for me to keep this person alive.
Only the Empire has issued a bounty. That "don't communicate" is from the Empire.
The Federation and the Alliance are not involved in this, at least form what Salomé said (for all I know) - unless you take the comments about the Alliance, Federation and Empire of R. into account.
If all three super powers are involved:
There could be reasons why those informations are kept secret by the Empire, Federation and Alliance. That all three super powers apparently try to cover up something should be enough to at least make you wonder what all this is about.
Is Salomé really the right person to make a decision that might affect a lot of people? Would you let her decide for you just because you don't like the superpowers?
Out of game view:
All those I quoted offered interesting and valid opinions and reasons. Thanks for that, I enjoy such conversations.
As a player interested in the story and the progression of the story I surely want the character Salomé to survive the April 29. event and I hope she will reveal interesting information.
At the same time I'm a bit struggling to find good reasons why my in-game character should care about what happens to Salomé.
That said, I'm enjoying this episode of Elite Dangerous. Thanks to all who are creating this (especially Drew)
