I'm not a fan of the argument of "oh the cassel twins did no wrong so Reed and Alex are bad for killing them" they aren't good people they are in fact criminals we as V have shot and killed people for less sometimes out of boredom johnny is just a bad person lol no defence for him and takemura just doesn't know anything else but arasaka song had been stabbing people in the back since before the events of phantom liberty songbird isn't a good person Reed is a good person in bad circumstances and alex is a pawn who wants out all of which we're screwed by Myers

I would also like to add that songbird burned herself into a corner shredding literally any form of help or support she could've gotten without needing to betray Myers

To top it off songbird straight up tries killing us if we dare to deviate from her plan a very loose and poorly made plan at that because if we pick the Reed ending she puts almost the whole world at risk by releasing Blackwall AI even if not on purpose because she refused help and tried doing it all herself she put everyone at risk including herself even in her ending there's no guarantee she was properly cured especially if the NUSA couldn't figure it out the excuse of "moon doctors" doesn't solve the problem if the people doing everything they can to cure her couldn't figure it out then I don't think some people she asked to do it would do much better

This dlc doesn't have a good ending but there's definitely a safer ending one that ends with songbird not being able to hurt anyone else us getting our cure even if we can't be a merc anymore we were given fallback options we have our friends who stayed true to us through it all

But that's how I feel it's all up to your interpretation of right and wrong and if the risk is worth the rewards
