How good of Brenok to do that! I wish that glinn could've been executed too, but I guess we can't have everything--and getting the women and girls away was obviously the most important thing.
For Brenok to see (or at least hear about) the very ugliest things that Cardassian troops have done is very, very important. It's one thing to serve the state, and to fight people who are fighting you, but to use your power to coerce other people and to violate them is just horrible and the fact that the Cardassian leaders allow such things to go on unpunished just shows how corrupt they are. Seeing that corruption will no doubt have an impact on a young Brenok.
