vermicious knids or many mouths to feed

Although my Venus Flytrap seems to be thriving quite well—despite the dietary restrictions I’ve enforced and certainly don’t want it to suffer any malnourishment in the meantime, it is rather presenting me with a moral dilemma.
To begin with, I wonder what my ward might think of me being a vegetarian, not a carnivore—however passively, but a committed planter-eater, ravenous even. The opportunity to sacrifice an annoying indoor housefly, usually a persistent and irritating occurrence but presently the apartment is strangely silence, has not yet presented itself and I am not sure, unable to swap a pest but only shoo it away, if I could avail myself to the task. I admit that it’s probably a silly thing to rend my hands over, but I’m hoping that I might get away with a crime of omission, that the balcony might an adequate environment for insects in transit or find some unfortunate bug dead or dying of natural causes or not wholly splattered and disintegrated on the car’s grille. I don’t know if that would work. I bet the other, more sessile plants are getting a little jealous of this sort of doting and negative attention. What would you do?
