A shadow

I've got a bit of a death shadow hanging around me lately. 2 humans and two cats that have gotten close in to me in the last three years are dead, all in unusual ways.
Dunno what it is, or if I'm directly responsible. But I'm the one outside thing that entered their lives. and now they're dead, all from unusual causes. Two women dead, one choked on her own vomit, one died the day a new liver was available to complete a transplant for her. The cats I won't mention.
In all cases I enhanced their lives, either gave them new freindshop and perspective, or gave them happiness in the case of the cats.
And now they're dead
Interesting.
