What villain actually had a good point?

I was going to write about some superhero origins story but then I witnessed this epic fight in my mum’s garden.

She has been concerned about what is eating her kale and she realized it was a caterpillar or worm.

She called me to look at the culprit and what did I see on the side ? Initially it was two ants trying to attack a caterpillar. Then another one quickly arrived to help.

I’ve been having some ants in the house and I love butterflies so I thought “what the heck? Let me save it.” But a little research told me that ants are natural pest control so the “villains” may actually have a point or purpose. Besides, every national geographic documentary I ever watched tells you that you are there to observe not intervene; but sheesh poor caterpillar, the unlikely villain.
