I could agree for Dex, for those who want a revenge. For me, it's not really necessary, he is just a poor guy who want to save his "large" skin
But compare Evy to Sandra is not really appropriate for few reasons in my opinion
- Money
Sandra is a "high corpo" and has a "platinum" trauma team subscription (the best I think). Evy is nobody, has no money. And even if V gives her some, I don't think you can go and request a Trauma membership like you would order a hotdog.
- The trauma
Sandra has been captured, hacked and stored while waiting to be "dismantled" (a bit like V in Sweet Dreams). Evy was abused for 3 days by Woodman without being able to react but being conscious. Then "exploited" by Scavs in the sordid basement of a factory (for I do not know what horrible and still being conscious).
- The reason of her suicide (the most important for me)
We don't really know why she committed suicide. Whether it's because of the trauma or if it's because she realized that she was responsible for the disaster (and the deaths), for putting Judy in danger and her dream of leaving Night City with Judy is simply dead. If that's it, I'm not sure a simple memory wipe (like Sandra) is really effective.
So to say, V can pay for save Evy (like Sandra), seem pretty "simpliste" for me
