Answer:
we can see that as the story begins john proctor has the external conflicts of providing the truth without being condemned. he struggles to keep his wife safe and his name clean. as time goes on he looses more and more of his morality even threatening to kill Mary to try to save his wife. at the end of act four right before john is executed he has the internal conflict of realizing all his immoral choices. he spent his time in jail reflecting on how he acted. when given the option to escape death, he refused, for it would require him to lie. to salvage what was left of his innocence he excepted his execution and believed himself to die a good man.
