Maid of Doom can have something pestilence-related. Lil black creatures reminiscent of common plague-carriers? Like strange sick canines, bats and rats? Maybe some birds to mix. Or they can have undead. While Rage Maid can have... demons? It's not like HS has canon angel-analogue.

HS does have Angels though, just not Rage equivalents, so it’s hard to tell. And Doom and Life are always weird because, pestilence and plague sounds Doom-y but it’s also tied to Life in the sense of microorganisms and sickness being biological stuff. Similarly, Undead could be Doom-related, but it could also be Life since it’s a body brought back to Life. There’s a weird divide when it comes to the biological part of Doom and Life, and I can’t quite decide which one sounds better.
