Freaking Klingons! A Reaper ship! I'm with Kirk on this one. They are animals. Let them die.
In this series they represent Death itself. There's precious little honor to go around. All the noblest acts belong to L'Rell, and even she kills off Voq's Klingon self to serve the greater good. She's also quite willing to destroy the entire race unless it unifies under her wisdom. Yikes!
Well, they are finally presented as an alien race with very different cultural values and norms. They're not just warrior humans with honor and bumpy foreheads.
