I feel more guilt when I kill any insect than I ever do when I hurt another human. Dunno why. I mean I love bugs to death so that could play a part in it. Like I cried when my stick bugs died.
No, and it's hypocritical for someone to feel guilt for killing an ant yet have no shame destroying a spider, fly or cockroach because "eeew it's gross!". You can kill one insect, you can kill them all. Just be glad they can't feel pain and don't have a life outside of biologically-programmed slavery
Can't feel pain now? What makes you think that? And humans are just as much slaves as they are. They react according to their environment, we react according to our environment.
I just read somewhere that while they can feel basic sensations (so they can respond to their environment, avoid predators and detect potential food) they don't feel pain (or pleasure for that matter) to the same extent as larger animals with more complex nervous systems, especially humans Same goes for all kinds of low-end animals, such as many land-based and aquatic invertebrates (worms, anemones, starfish, etc) which are often at the bottom of the food chain and at the mercy of even the gentlest breeze or current. Feeling pain would be a huge disadvantage to animals like these who would probably spend half their lives experiencing it if they could
