Kazon are actually extremely fleshed out compared to other species in Star Trek. Their society of independent sects all working together (after Voyager) known as the Kazon Order is actually kind of cool. If it weren’t for their treatment of their women they’d be half alright.

But, their design, they way the Borg deem them unworthy of assimilation, the way they needed Voy to help them truly come together, idk something isn’t right there.
