for good or bad

is this some threesome or what
where the angel finds the devil too hot
and god takes offense too fast
on the tough member of the cast

find it fast, that thing you lost
somewhere in the depths of the past
when the twain split for good
and left a shard that stood

the one with both good and evil
working on every whim and will
where being good is a struggle
and being bad is clearly trouble

angel, you may choose to call it
by name, if only you see it fit
but what it is the two must see
a part of both she must be
