He didn't kill half of infinity, he killed half of all living things in the universe as an offering to Death
That is a finite number of things
He could have killed 2/3 of them or 1/5 of them or 2 of them
Too deep in yearning we need
something to hold, and something to keep
Innocent eyes could not realize
the meaning of "destiny"
But someday I promise that
you’ll start to notice what’s there on your shoulders someday -
Wings that are strong,
they will guide you along to the future that holds your fate!
Let me tell you a cruel angel’s thesis -
Flying high from the window, finding egress
There is something betraying all my memories,
burning pathos, emotion overwhelming!
