insects are the closest thing to biological robots, clever little automatons w/ complex behavior, social structures, capabilities
if you wouldn't kill a bee, why a roach? they're even less able to harm u. this is cuteness privilege
(if you'd kill a bee pls unfollow asap)
if you've never really thought about this before, I'd urge you to reconsider your automatic reactions to icky bugs; do you really need to kill them? or are they just an eyesore?
if so, maybe you can try to see the beauty in them; all life is sacred, even ugly unpleasant life
