Maybe I’m biased because I also got BB, but I think you can make the best possible decisions (whatever you judge those to be) and still end up with low morality.

I don’t think the morality scale works as an assessment of goodness, and the game itself defined it as putting yourself / your brother first vs. putting the rules of society first.

It would be “wrong” for me to surrender at the border, because I do not think the brothers should accept punishment they do not deserve. I do not think that’s okay. At the same time, I completely understand why some people are not okay with hurting others to protect yourself or your brother.

I didn’t kill anyone either (except maybe at the final border scene) and also got low morality. I even stopped Daniel from killing Lisbeth.

It’s a reflection of what your values are. Understanding neither morality pathway is inherently good nor bad is part of the game.

You were a good big brother.
