>>281220165The key is the antispiral out of fear has become antiprogress while Team Gurren is all for progress.
The issue is there is a truth to what the antispiral says if Spiral Energy continues growing unchecked it will destroy the universe. The entire final battle the antispiral is scolding them for letting their spiral Energy grow so unchecked and wild. The antispiral upon revealing the true nature of their race and the sacrifice they made in their belief they could save the universe even if it meant destroying any Spiral Race who advanced to far demands to know if Team Gurren has the will to go to such lengths.
>Anti-Spiral: Foolish creatures, drunk on your Spiral power. Do you possess the resolve to do that?>Anti-Spiral: We defended the universe by killing our fellow Spirals, and halting our own evolution.>Anti-Spiral: Do you possess the sheer fortitude that is on par with that?! DO YOU?!>Anti-Spiral: We say, NO NO NO NO NO NO NO NO NO NO! NOT! AT! ALL!!!>Anti-Spiral: You possess neither will! Nor resolve! NOR REASON!Simon's own response is that the Antispiral's decided that on their own.
Anti-Spiral: That is the path that leads to extinction. Why can't you see the pathetic limitation of the Spiral race?
Simon: No, that's YOUR limitation! You sit here, closed-off, locking away other lifeforms like some kind of king! That's nobody's limitation but your own!!
Leading to the final big speech.
Mark my words. This drill will open a hole in the universe! And that hole will be a path for those behind us! The dreams of those who have fallen... The hopes of those who will follow! Those two sets of dreams weave together into a double helix, drilling a path towards tomorrow! And that's Tengen Toppa. That's Gurren Lagann! My drill is the drill... THAT CREATES THE HEAVENS!!!
Simon recognizes the sacrifice he, Nina, Lord Genome and the AntiSpiral made is to drill the path that will lead to defeating the Spiral Nemesis.
