Final answer:
Hamlet's attitude towards his father as a king and husband is one of disappointment and disgust.
Step-by-step explanation:
In Hamlet's monologue, he reveals his attitude about his father as a king and husband. His attitude is one of disappointment and disgust towards his father's actions and his mother's role in the situation. Hamlet sees his father as a loving and respected king, but he is deeply hurt and betrayed by his mother's hasty marriage to his uncle after his father's death. This is evident in Hamlet's soliloquies and his interactions with other characters throughout the play.
