Revenge of the Abused Kitties

Every now and then, after I gratuitously kill an insect, I go into this weird thought space: I wonder what would happen if, one day, I opened the front door and outside was a huge, Kafka-sized roach, fly, or ant, there to avenge all the insects I’ve ever murdered, en toto.

What would happen? What would one see?

Probably something like this, above.
