It depends on the characters, and at which point in the story. While Victor is creating his monster, he does not speak to anyone. Instead he becomes a recluse and obsesses over his creation for months.
After the monster is created and comes "alive," Victor becomes absolutely frantic and his attitude toward Henry is weak and desperate. He describes how Henry has to nurse him back to health.
His attitude towards the creature is irresponsible and downright scary - if you believe that he is the creature's father. He completely disowns him and is ashamed at the hideousness of what he has created.
