That’s a really good question and no one has ever asked it before, so points for originality.. 🙂
Had they known that their surprise magnum opus was going to end up fizzling duds the two would not have carried out the massacre that day. They would’ve regrouped and delayed the massacre – just a bit but not too much longer – to ensure their plans would go accordingly. I think especially for Eric it’d be a case of no bombs?; then no NBK. Go hard or go home. It’d drive him nuts to know that bombs had been useless all this time they were smug they’d just go off as they envisioned and not only that, they weren’t even going to explode weakly but basically not at all, period. It’d piss him the hell off that he’d overestimated his work and hours of time and preparation and they were basically both operating on faith and assumption that the bombs would go off and not on concrete testing to make sure they’d succeed in all there efforts.
If they were given the information that these bombs were just never going to rig the right way and explode at all, whatsoever, they would then have concentrated on a backup ‘Plan B’ which might have amounted to the boys concentrating on using what they already had on hand as far as weapontry and terrorist instruments of destruction.but maybe creating additional incendiaries and pipe bombs They also might have focused their efforts on the slim chance that that nepalm weapon invention of theirs might do the trick and make them stand out as that school massacre with ‘something extra’ to be remembered for These two were just hell bent on NBK happening no matter what. The revolution would be kick started with any sort of ingenuity they could muster on a shoe string budget and in the small window of time they had left before graduation. Though, no big bombs, in that nod to McVeigh plus surpassing kills style, would’ve been a major let down especially for Eric. For Dylan, it would’ve been all good no matter what method to their madness they decided to implement, though seeing Eric ecstatic that everything went according to plan would’ve been a bonus, of course.. 😉
