I think that Blackie's leadership model is geared more towards the greater good than Trevor's. Prior to Trevor asserting control, Blackie demonstrated himself to be a leader that was more concerned with the group remaining intact and as a collective unit. Trevor's plan to destroy the house seems more individualistic. His leadership model is driven to satisfy his own agenda. This is realized when the group starts to question why they are doing what they are doing. Trevor cannot give them any justification on a group or collective level because this was never part of their "buy in." Part of the reason that the group gravitates back to Blackie is because he has focused on the group's well being and status as part of his consciousness. Even when ousted from leadership, his frame of reference is one that is driven by the group's interest as opposed to his own. It is here in which the leadership style of each is fundamentally different. Trevor is unable to maintain the cohesiveness of the group because he never leads with the group in mind. To put it in another way, Blackie demonstrates a leadership model that is intended to serve the needs of the group, as a whole, while Trevor's is more individualistic.
