I kill ants all the time in my office, then right afterwards I feel bad. They’re innocent, obviously, just searching for whatever it is they’re searching for (food, materials, other ants, adventure).
There are two reasons I feel guilty: it’s killing something, and it’s destroying a perfect creature. All living creatures are perfect to me because they somehow made it this far in their species evolution to be able to live and procreate on this planet.
If you look at ants or any creature for that matter close up, they’re brilliant. No human could have ever thought of creating something like that. It’s totally amazing, and that’s why I’m at odds with killing pesky creatures.
