I think when talking about Damon as a follower, you can take even further. Damon's actions are dependent on self-gratification and personal interest. If he does a noble or heroic thing he is probably benefiting from it. Stefan at least attempts to do heroic things without necessarily expecting praise or a reward. Sacrificing himself to save Damon, sacrificing to save the twins. These situations don't benefit him in anyway, but he wants to help.
