"It is better to die for what you believe in rather than lie to save your life".Write a persuasive response for or against or a personal reflective...

I agree with akannan, and I think the choice has been made
for you by the prompt (which is a good thing, since few of us in America, at any age,
have been faced with anything as dramatic as dying for something we believe).  The
prompt says to cite specific evidence and quotes from the play, and Act 3 is the place
to look for them.

Here, there are 4 characters who die for
their beliefs:  Martha Corey, Rebecca Nurse, Giles Corey, and John Proctor.  Proctor is
obviously the most dramatic and fleshed-out of the four, and you've already gotten some
good ideas for that.  Consider the two ladies, who are appalled and dismayed that
John--who they obviously consider to be one of the righteous, despite his glaring sin of
adultery--may sign his name to a lie.  They understand as as he does that this would be
an eternal condemning of his soul according to their fath, as well as a reason for the
trials to continue.  They neither scold nor rebuke him harshly; they're simply saddened
that he has caved.  They, meanwhile, continue to stand
firm.

Giles Corey is unique in that we hear about his death
second-hand--though that doesn't make his death any less dramatic.  In fact, it's one of
the finer moments of the play when we realize he was able to look his accusers in the
face and clearly refuse to confess.  His "More weight" is a hugely impactful line and
clearly an actual decision to die for a cause (and to save his childrens' inheritance,
of course).

This should be fun to write.  Good
luck!
