Is there a name for this specific concept? Where somebody invents something (to do them good) but then that thing turns around and backfires on them?
A name for this?
Isn’t it ironic, dontcha think?
It would only be ironic if it were a lifesaving device, for instance, if the creator of the defibrillator went into cardiac arrest by an accidental misfiring of the defibrillator on him.
Irony requires a reasonable expectation of an opposite outcome.
A solar eclipse happening on a cloudy day is not ironic, it’s merely unfortunate. A song about things claiming to be ironic actually containing nothing that will qualify as ironic is ironic.
