I don't Ben is trying to be displayed as a possible 'hero' of Lost. I just think it's fascinating how he went from the ultimate bad guy to a member of the survivors. Not a full member, just a semi-member that the other people are still looking at with suspicion and doubt.

I don't think Lost has heroes at all. Even among the 'good guys' there's not really a good guy there. Kate killed her sleeping father, Sawyer shot and killed an innocent man in cold blood, Sayid was a torturer, Jack was, at best, a neglectful husband (not a horrible crime but still not a good thing) and at worst a stalker of his ex, Locke talked Sawyer into killing his father for him. Nobody is really hero material.
The only difference between Ben and those I mentioned above is that we know Kate, Sawyer, Sayid, Jack, and Locke had good reasons for what they did. Their motivations were clear that they were doing a bad thing for what (they thought at least) were good reasons. We don't know what motivates Ben to do the things he does and did. Maybe he has really good reasons too. Maybe better than "I killed him cause I thought he ripped off my mom and dad causing them to suicide. Oops. My bad."
Us not knowing what the Others are doing or why is part of the mystery of the show. Maybe everything they do is to save the world or something else spectacular. If that's the case, then kidnapping Jack, Sawyer and Kate and forcing them to...... wait. What did Ben do to them while he had them kidnapped that was horrible? Kept them locked up and lied to them sometimes. Asked Jack to save his life? I guess Kate and Sawyer did have to break some rocks for them. Terrible! Sarcasm aside, all of that can easily be justified if the reason is good enough.
Maybe that's the whole point of the show. Kate can kill her dad if he's mean and possibly abusing her. Sayid can torture people if it's his job and he's really, really sorry about it later. Sawyer can shoot and kill an innocent guy if he really thinks he's the guy that caused his parents murder/suicide.
Motivations. If you have a good enough motivation, you can do whatever horrible thing you feel is necessary.

All we need now is to know Ben and the Others motivations.


Oh, and I was lying before. There is a hero to Lost. The one and only Vincent! Vincent the pure, Vincent the brave, Vincent the HERO
