Well, since it's not exact science we are talking about the "correct" can only mean something totally subjective.
So I might not think ever the correct solution to use a murdering idiot with a gun.
Not least because that implies having (and keeping) murdering idiots.
That's one example why I would label that as an incorrect solution.
No, it's a blind playthough, no spoilers for the brand new eas war that just dripped!
