It's just a fly. It doesn't even feel it because the first shot puts it to sleep. On a serious note, flies are disgusting. They eat their own puke. Maggots are disgusting so I just kill them.
Flies may think we are disgusting because we don't eat are own sick but do they brutully murder us ?? nope
But they don't do it on purpose.... Atleast i don't think they do unless they are planning too wipe out the whole human race by spreading diseases
Oh man in that case we must have a meeting and bribe them, we shall offer them dog shit too land on and if they decline.... We get robin hood too shoot them all with his merry men
