Most spiders are pretty sweet. I'll have to tell you a couple of black widow stories someday.
You made some great points. I am a licensed wildlife rehab, exotic pet as well. You do imprint on what you try to save. One pretty significant point you brought up, and I had to think about it, still haven't come to any conclusions
but you do have to really think about what and how you are doing it... and even why are you doing it
I think it was the why that really made me think. I do know how to leave as little imprint has possible. But, why??? I fed bears but never brought a full grown one in the house, mostly because it won't fit through the door. Have brought cubs in though. I have had wild cats inside. Not to tame as pets. Wolves, yes, foxes, raccoons, many mammals to many to even remember them all. Birds, reptiles, bugs of all types
You are responsible for what you have tamed
I don't think people realize how responsible they are, or for how long, as long as it is convenient?
