The first time Kenny died, he wasn't scared. Life was done, simple as that.
When he came back, he was terrified. Then he calmed down. Got over it.
Second time, it was nothing. He stopped caring when he came back.
Third time he decided it was a cycle.
Every time after that, he expected to come back. Even if he didn't come back right away, he did in the end.
So he just relaxed.

This time though-
he came back as a she.
