I wouldn’t kill a butterfly, but I wouldn’t kill a spider either. The only bugs I kill are mosquitoes because it’s the most efficient way to get back to sleep. I’d be okay with giving blood if it wasn’t for that awful noise they make
Yeah I usually only kill spiders and ants when necessary. They have infested my neighborhood so I have no choice since they will literally bite me at night. But in doing so I have less guilt than if I was exterminating a butterfly nest.
