Those spiders you find inside may be of a type completely adapted to living indoors with humans. Putting one outside means death.
I made this mistake with a stink bug when it was winter. It was ok with being on the piece of paper I had it on. When I opened the door and the cold air hit it, it backed away towards me. I set it down and it stopped moving. Oops. :(
Aren’t most bugs cold blooded?
