Which lines in this excerpt from shakespeare’s richard iii provide evidence for the theme of good versus evil in the play?
richard iii (duke of gloucester): now is the winter of our discontent
made glorious summer by this sun of york;
(a) and all the clouds that lour'd upon our house
in the deep bosom of the ocean buried.

now are our brows bound with victorious wreaths;
our bruised arms hung up for monuments;
our stern alarums changed to merry meetings,
our dreadful marches to delightful measures.

(b) grim-visaged war hath smooth'd his wrinkled front;
and now, instead of mounting barded steeds
to fright the souls of fearful adversaries,
he capers nimbly in a lady's chamber

to the lascivious pleasing of a lute.
but i, that am not shaped for sportive tricks,
nor made to court an amorous looking-glass;

(c) i, that am rudely stamp'd, and want love's majesty
to strut before a wanton ambling nymph;
i, that am curtail'd of this fair proportion,
cheated of feature by dissembling nature,
deformed, unfinish'd, sent before my time

into this breathing world, scarce half made up,
and that so lamely and unfashionable
that dogs bark at me as i halt by them;
why, i, in this weak piping time of peace,
have no delight to pass away the time,
unless to spy my shadow in the sun
and descant on mine own deformity:
and therefore, since i cannot prove a lover,
to entertain these fair well-spoken days,

(d) i am determined to prove a villain
and hate the idle pleasures of these days.
