Wow that behaviour sounds very parasitic, living from the life force of the host until the host dies then finds a new host. Sounds like they’ve done that sort of thing before, I’m sorry that happened. I’m sure they’re already paying for it in some way.
Things didn't go well for them from thereon stuffs. Sad as I know people do stupid things out of desperation, but if you could think up that much wrong you could have surely thought of ways to do things right.
Oh absolutely, some must take the more treacherous path in order to evolve, however it’s not nice when it involves others that mean well
