Are you talking about Nick or Locke?
Nick basically doesn't care about the others but owen only. Yes they have all the evidence they need to expose everything that happened and to give justice to the victims, but what comes if he exposed it? The whole rose family will be held accountable, owen too. And it will also be a big scandal of owen since he is also one of the victims and the story of him being a "monster" might be exposed. Owen also owns a pharmaceutical, netizens might think that owen is actually part of locke's schemes to use them to his business. Again, nick only cares on what's gonna happen to owen.
Umm.. he was never portrayed as a green flag.
He's an x military, so he's not gonna be the goody two shoes you looking for
Fuck all of you, there were no reason for this shit ending other than proving that Nick is an hell of a red flag burning in flames. Other that all of the omegas that shit villain tortured did he forgot Owen's parents were victims too? That maybe Owen would want to hold them accountable? Nick is treating Owen as a possession and people are still acting like this is he trying to protect Owen. The author totale fucked up if that is the ending and with no scuse. Also, fuck anyone who said that is ok because Nick is already dead, the family of the victims deserve to know what happened, if you are being this insensitive and still asking people to be realistic (which is a crazy thing to say in this site) I hope you find a Nick someday.
