Possessed by something like the oni?

Possessed by anything that could make them evil.

It really depends on the situation. As we’ve seen him willing to kill a kid(well teen technically) to save a baby(Hope). So I’d say it’s possible. Especially if he found out that this kid can’t be brought back or be unpossessed. But most likely he will probably let himself get killed. 😎

I feel he would kill for someone he loves if they were in danger (like davina or hope) but not for himself y'knkw

He can't be killed
