Can someone sum up what Hamlet's inner conflict is in the play Hamlet?

Hamlet's inner conflict centers around whether or not he
should enact revenge upon his father's murder, or not.  Wrapped up in that conflict are
questions about whether the ghost of his father was real or not, because if not, then he
would be murdering his uncle all because an evil ghost prompted him to.  Also, Hamlet
wonders whether or not he is capable of murdering his uncle; he spends so much of his
time worrying and fretting about it, and so little time actually doing anything that he
gets mad at himself for inactivity.  It takes Hamlet the entire course of the play to go
from a man who is fearful and hesitant and wallowing about "in words" to a man who can
stand up and declare, "the readiness is all."

Before he
learns of his uncle's betrayal and murder of his father, Hamlet's inner turmoil was
caused by his distaste of his mother's actions in marrying so soon after becoming a
widow.  This conflict within him makes him so upset that he declares Denmark and
everything in it "rotten" and vile.  He is grieving for his father while at the same
time seething over his mother's quick recovery and marriage.   Once his father's ghost
visits him, that conflict soon turns towards his own struggle to enact revenge.  I hope
those thoughts helped; good luck!
