I think one of the most interesting things about this series is the fact that none of the characters seem to have any problem with killing throughout the whole ordeal. Characters who make incredibly huge deals about how important preserving life is to them have no problem blasting away at alien scumbags with lethal weaponry, and blowing them up death star style. I wonder if that ever comes up again. There's sort of like this unspoken rule that it's completely okay to kill aliens. Guy Gardner commits cold-blooded murder multiple times, even killing at least one innocent alien, and he barely gets scolded for it.
