The fact that Gertrude married Claudius only two months after the death of the king is preposterous to Hamlet. He does not understand that if Gertrude really loved the king how she could move on so quickly. He frequently complains about it, and reveals his anguish over the fact the Gertrude was so upset at Old Hamlet’s funereal, but quickly overcame her seeming grief. A little month, or ere those shoes were old with which she follow’d my poor fathers body, like niobe, all tears:--why she, even she—O, God! A beast, that wants discourse of reason, would have mourn’d longer—married with my uncle, my father’s brother, but no more like my father. Hamelt not only has an issue with his mother’s quick remarriage, but is also disgusted by the fact that Gertrude is guilty of incest. He says “She married. O, wicked speed, to post with such dexterity to incestuous sheets! It is not nor it cannot come to good: But break my heart; for I just hold my tongue.” Hamlet desperately want to let everyone know the wrong that Gertrude is doing. By holding all of this in he just becomes crazier. He cannot stand to watch Gertrude and Claudius be so in love, and seem like nothing happened to his father.
Hamlet is at war with his own feeling of whether or not, or how to avenge his father’s death.
