I distinctly remember this episode as the point where I began to think Picard's high minded 24th century morality began to go off the deep end. I asked the same questions Ms. Green did: what accord can you reach, really, with an entity that devours whole planets? I suppose we are to believe that, given the time to talk it out, the entity would have transmitted the equivalent of "Oh! I had no idea, I'm so sorry!" This tendency to assume that compassion and remorse is universal is one of Trek's great shortcomings. Some enemies are not misunderstood yet noble adversaries, they are simply predators or forces of nature. Marr may have been imbalanced, but I can't really say she did anything wrong except take matters into her own hands.
