CASCA
Three or four
wenches where I stood cried, 'Alas, good soul!' and
forgave him with all their hearts. But there's no
heed to be taken of them; if Caesar had stabbed
their mothers, they would have done no less. (1.2.282-286)
Casca suggests that public opinion is easily won and is therefore meaningless. Plus, even though the Romans are supposed to be a republic of equal citizens, those in charge think everyone else is dumb and treat them accordingly. (All Romans are equal, but some are more equal than others.)

CASCA
I can as well be hanged as tell the manner of it.
It was mere foolery; I did not mark it. I saw Mark
Antony offer him a crown (yet 'twas not a crown
neither; 'twas one of these coronets), and, as I told
you, he put it by once; but for all that, to my
thinking, he would fain have had it. Then he offered
it to him again; then he put it by again; but to my
thinking, he was very loath to lay his fingers off it.
And then he offered it the third time. He put it the
third time by, and still as he refused it the rabblement
hooted and clapped their chopped hands and
threw up their sweaty nightcaps and uttered such a
deal of stinking breath because Caesar refused the
crown that it had almost choked Caesar, for he
swooned and fell down at it. And for mine own part,
I durst not laugh for fear of opening my lips and
receiving the bad air. (1.2.245-261)
Caesar deliberately deceives the public here. It's clear he's putting on a great show by refusing the crown, even though he'd secretly love to have it. He understands that public refusal is a smart political maneuver to get the people to love him more and think him less ambitious.

CASCA
But wherefore did you so much tempt the heavens?
It is the part of men to fear and tremble
When the most mighty gods by tokens send
Such dreadful heralds to astonish us. (1.3.56-59)
Casca has fear before the gods, while Cassius interprets heavenly interference as a sign that his traitorous enterprise will go well. Cassius is arrogant in his interpretation that the gods are on his side, while Casca displays humility.
