There goes your karma. I'm only kiddin, you can probably fry it and eat it as a snack, full of protein filled crunchy goodness. I just remember this documentary from south asian region somewhere, kids love to catch and eat tarantula over there, they love that stuff as snack meal.

I have this one spider nesting outside my window right next to this A/C unit, it's shed a few times, producing offsprings, I think guessing from how long he's been living there, he's been fed good, meaning I'm having less chance of bugs flying around near my window.

I understand it though, if I find some bugs inside, either for flying or crawling kind, my first instinct is to kill it. Sometimes it leaves more mess than to catch and release them into the wild, not to scare you or anything, but I fear a bit about revenge from insect kind, it's not phobia but I wouldn't want anything to lay eggs inside of my ear, so I try my best to be nice.

Was it fast moving kind? That would scare me good. It was unavoidable property dispute, it could've bitten you so, a self-defense claim stands, you may continue to live there peacefully, court adjourned. *gravel down*

Hmm...you won't be eating what you don't want to eat, what I eat is kept safe, I wouldn't worry about it. And here's one more thing. I usually think that if I kill/release one intruder at my place like that, unless I see uninvited guest all the time, I'd be better off probability-wise. It's not too late to think about the sacrifice, so the current occupant of the property can sleep as sound as possible. This's just my 2 cents.
