What is the foil (difference) between Antigone and Ismene?How are they different? I know that Antigone is for the God's rule, and Ismene is for...

Antigone is certainly much bolder and more independent
than her sister is. In the play's Prologue after Ismene tells Antigone that her plan to
bury their brother's body is impossible, Antigone
promises,

"If
you say this, you will be hateful to me, / and the dead will hate you always–justly"
(93-94).

The title character
is not afraid to alienate her family and friends--even her own sister--in order to do
what she believes is her moral obligation.

While many
audience members might agree with Antigone that Ismene is a coward, Sophocles suggests
in the Prologue that perhaps she is simply not as hot-blooded as is Antigone. While
Ismene also loves her father and brothers, she realizes that infighting has brought only
death to her family, and she does not see the point of continuing the feud (it would now
be between her and Antigone and their Uncle Creon).

In the
end, both women possess admirable qualities. Antigone's strength and boldness allow her
to affect her uncle and all of Thebes before she commits a martyr's suicide, and
Ismene's calmness allows her to bring hope of a more peaceful future for Thebes when all
the carnage is done. She is the only female family member left alive at the play's end,
and it will be up to her to decide if she will continue following the laws of man or if
she will try to assert herself as a woman.
