Roemig got exactly what was coming to him.
Justify this statement.
We know very little about Roemig or the Trinity, other than that they defected to the NTF only shortly before they were encountered in the nebula. (I think it's 9 days, but I might have that number wrong)
Just because the majority of the NTF hated the Vasudans doesn't mean that's why he joined. It's fully possible he had some other motivation for defecting--it's even possible he was forced into it by a mutinous crew, and might have risked being tossed out an airlock if he didn't go along with it. Or maybe he had some personal reason to switch sides? There is almost no information on the character of Arthur Roemig.
Heck, Bosch (or whichever of his direct subordinates gave the order) probably sent the Trinity because they were the newest ship to defect (and thus the one whose loyalty was unproven and whose crew mattered least in the bigger picture).
I'm not saying that he WAS a good guy (like the Good Samaritan, but NTF instead), but this seems a bit over the top to me.
