Severed Dreams - I don't have much sympathy for the soldiers who die fighting for Clark. He's obviously gone far outside his powers, so if the good guys have to blow up the earth ships working for Clark, its the fault of the guys loyal to the president. Like Sheridan has pointed out, the soldiers are supposed to be loyal to Earth, not the president. It may suck for Sheridan and the good guys to fight them, but the idiots didn't leave them much choice. At this point, the president is obviously going far outside the law. If they support him, they should be prepared to get killed for their stupidity. I say the same thing about the majority of Earth's citizens. the fact that most of them support martial law (while the colonies see that its evil), and the fact that the soldiers will bomb civilians with no hesitation because they are so loyal to Emperor Palpa...I mean the president, just makes me want to see the Shadows attack earth. If they wipe it out, then a pit of evil will be gone from the universe, and there will still be enough humans in space and on the colonies to continue the species. Hopefully the good guys will let the shadows destroy earth before trying to stop them
The people fighting for Clark believe that they are being loyal to Earth and view the colonies and places like Babylon 5 that choose to go against the presidents orders as the disloyal ones and or corrupted by alien influences. I can't condone actions like bombing civilians but I imagine the pilots got caught up in all the anti-sedition talk and things like Nightwatch and fear of open rebellion and chaos, makes it much more believable that some of them could be a part of atrocities committed during the Earth civil war. Clarks forces aren't the cackling evil mustache twirling villains you make them out to be, it's not a cut and dry good and evil conflict. That and not everyone on Earth agrees with Clark and his policies (see the honest non-shill ISN reporters for an example). I don't want to get into spoiler territory but there are some reasons that the Shadows won't openly attack and destroy the Earth the way they helped the Centauri bring down Narn.
