Fighting is Fun!
Alas, this is an observable fact. But not to despair; after all, no one turns out to be more committed to nonviolence (and the fact that fighting as a way of life can also get so old as to be downright tedious) than Vash the Stampede, hero (?) of the anime series Trigun: a Messiah-figure if ever there was one.
So here's to invincible, heroic, larger than life fighters who can crush you like an insect but would never hurt a fly.
