Tsukasas reason still makes no fckn sense, he believes not everyone can get safed... so he is beeter off killing them in advance?? And Senkus plan is to save everyone... and Tsukasa is against that??? It makes no sense.
the strength granted to humanity by nature is intelligence. a chimpanzee is smaller than we are, but much stronger. but which of us do you see running the world, strong chimps, or intelligent humans? strength is nothing without the intelligence to use it effectively. eventually, the strong will always lose to the intelligent. strength will beat you to death with a stick, intelligence will turn that stick into an arrow, and kill you before you even know they are there.
