Cloudyheart, my favorite cat, was murdered and there is DRAMA

This guy, who has an awesome backstory, personality, and cute design has been murdered.

Posyclaw a 'charismatic' half-Clan cat is the the known culprit.

Problem is my 'compassionate' leader is GLAD about this. So I don't think she'll be exiling Posyclaw.

His DAD is the medicine cat and he is upset. (And only one of his three siblings has a mourning thought.)

And his mate, the OTHER medicine cat, is grieving! Plus, Elkfern and Cloudyheart went on a cute couple's patrol last moon in which Elkfern tripped and BROKE HIS BACK.

Should I focus on sabotaging the medicine cats' relationship with Gracklestar or Posyclaw? My goal is to get one of them to murder their leader or the warrior in revenge (hopefully). Snowchase would probably be more willing to take one for the team since he's older, but Elkfern used to be a rogue so he has some edge.
