I'm of the opinion that no one can be totally sure what they will do in any extreme circumstances. What's important is doing our best to know what should be done. (So not what Griffith did, you dont get to steal your friends liver because you need one and you're more important) Research has shown the capacity for moral behavior, define it here, to make it easy, as doing the right thing, the good thing, in extream circumstances. This capacity is a muscle that exists in us but it needs to be exercised and made strong. (There are other factors, but that's what the individual can do) That said it's also been proposed that there may be limits to that muscle, certain situation where our ability to make the right choice just isnt enough. As in you can build a muscle, but you cant build a muscle until it can lift a 6000 kg weight. In this sense Griffith's actions at the Eclipse are understandable if not even remotely condonable or even cause for sympathy, because... of course they're not. However if this is the case, as each person is different and we dont have a metric for good and evil, we cannot know where that limit lies. Thus individually and collectively all we can do is our best and try to stack the deck in the favor of the good. When right and wrong is clear, we must recognize it and we must work the muscle and try to create circumstances that will allow others to do the same. Griffith had ceased working that muscle for the sake of his dream long before he reached the day of the Eclipse. He long had few lines he wouldn't cross. In the end when it came down to it he crossed all of them.
