Not necessarily. But on a Dante-esque scale of damnation, they definitely AREN'T at the bottom of the pit relative to the Others.

They weren't the instigators in the feud between the Others and themselves.

Rambo didn't draw first blood, and neither did the Losties.

If you don't want a fat lip, then don't initiate a fight and punch someone else in the nose.

The Others were up to over 40 murdered BEFORE the Losties ever arrived. Not entirely "good", now are they?

I am more prone to be sympathetic with the Losties at this point than with any other faction.
