Moretsu Pirates: Bodacious Space Pirates

Thanks
I don't know if this will be useful info later in the anime. But I guess that those with Letters of Marque probably did have pride in it and felt dishonored when compared to your average pirate.
I don't know if they'll get into that detail later in the show.

They were average pirates before they received the legal status. Some of them could have been real monsters but were enlisted nonetheless, as long as they were efficient at waging war in space. If the planet was desperate enough to try to get pirates to fight for them, I don't think they could afford to select those with honour and good manners... In fact, if they acted like corsairs out there somewhere, remorseless killers could have been all the better.
