Lilith and Max [Angst?] (Read Desc for context)

Context: Lilith became possessed/out-of-control and began attacking Max. They were, of course, in their beast form. They didn't expect this to happen... After the battle, they were both beat up pretty badly. Lilith's wounds were hidden and they were decaying, while Max's wounds were not hidden and he was dying. They cared about his life more than their own, so they saved him instead of themselves. Of course, Max was happy to see them and forgave them because he knows it wasn't their fault, but Lilith thought they didn't deserve to be called his sibling, nor did they deserve forgiveness because they felt absolutely horrible after what they did to him. Where did they run off to? The forest. They wanted to stay in that forest to die.. Max saved them though, but the guilt still swarms in Lilith's head to this day.
