26 Characters in Search of a Play

This poem is self-explanatory:
It consists of English words comprised
of permutations of 26 characters
in search of play. It means no harm.
It comes from a brutal universe,
where nice people hurt and die.
It doesn't have time to say much.
It would like to be useful,
because if play can be useful,
it will be permitted to play.
It means well.
It can't help itself.
