I don't know if you've beaten the game already but I don't wanna spoil anything so I don't really know how to respond lol

I've beaten brotherhood side go ahead lol. Use spoiler for others just in case I guess.

Alright [spoiler]If you complete the game with Institute you become the director and well you direct what they do so the whole kidnapping motive can change into helping people instead[/spoiler]

Oh ok yeah my friend went with that side and told me about it. [spoiler]I mean yea I guess technically then the institute can be considered good. For the entire time you're not there though the institute is kinda bad. Brotherhood isn't all great though too. They are only in it for technology. At least under elder Maxson though they're kinda for the people in a sense because he was raised around elder Lyons. [/spoiler]
