what has this has to do with scrum? I haven't even mentioned it (or even implied that this has something to do with scrum), dysfunctional teams are waaaay more general problem than whatever scrum is/isn't. Blame implies responsibility, which - like you mentioned - is not that simple. (Depending on personal philosophy maybe each team member has a responsibility toward themselves to get a job where they are not put into the aforementioned loony toones situation, but even with that in mind I honestly think you misinterpreted my comment, because I don't meant to assign blame at the team and its members. You might notice I expressly mentioned that if the team is too dysfunctional it has to be broken up "from above", implying that its not the responsibility of the team.)
