I guess it comes down to personal opinion.
I used to feel bad about killing them when I was young but nowadays I don't give it a second thought. Insects and spiders have been everywhere around here recently though because it's been an unusually long summer and are very annoying. I found a nest of spiders in my house the other day and sprayed fly killer right in there for atleast 30 seconds and as bad as it sounds, it was very cathartic and slightly entertaining to watch them flee.
