I also have this moral dilemma with the tomato hornworms. People are often like "kill kill!" and I dunno, I just can't. They're not doing anything wrong? Thankfully I actually haven't ever encountered one in person. I do have to say though is I LOVE THE HAWK-HUMMINGBIRD MOTHS SO MUCH! They're so cool, and they pollinate! Someone suggested feeding the worms to my chickens... I don't think I could do that either.

I very much treat my homestead as a "live and let live" type of place. If something is really hindering me, then I will have to take some sort of action, but until then, they're just living.
