Well,basically through those questions with answers that may be considered "good" or "bad"
like,how in the begining, when keroe asks wheter you are ready to risk your life to save these people.
If you say yes,it should be considered "good"
while,if you choose no,it would be nuetral, or bad.
I havent played long enough to see all these things,so I might be wrong,
but this is how it worked in the series.
