"i kissed the scars on his skin
i still think you're beautiful
and i dont ever wanna lose my best friend"

the black wolf-thing is hom.ocide, he chooses victims and "posses" them to ki.ll others then makes them ki.ll themselves.
but for moonsand's case, hom.ois trapped in him cause MoonSand is self destructive. so ho.mo cant leave til MS ki'lls somebody but he wont but MS cant ki.ll himself til he ki.lls someone else see the problem here?

so ho.mocide says this ironically
