He is shown to be very psychotic and violent (as shown when he "rewards" his son by giving him his first beer, upon learning he had killed Mike Hanlon's dog). Butch would often beat his son and wife on a daily basis. In 1956, Butch's wife eventually left him, after nearly being beaten to death by him.
He was very racist towards William Hanlon and his family, and would call William a variety of racial slurs. He even went as far as to kill all of William's chickens and to draw a Swastika on his property. Sheriff Sullivan supported Will's perspective and brought Butch into the police station to suggest that he pay $200 for the worth of the chickens because that way Will wouldn't press charges. Butch laughed and said that no jury would find him guilty of killing a nigger's chickens. Sheriff Sullivan agreed, but pointed out that he WOULD be found guilty of a hate crime because of the Swastika. Butch realized he was right and sold his prized Mercury to pay Will Hanlon, an action that made him hate the man even more. Butch's war against Will Hanlon only stopped when William pointed a rifle at him and threatened him.
After a violent rock fight in late July of 1958, Henry's sanity slowly deteriorates, not only from It's influence, but also his father's as well. In late August, he was killed by his son, who slit his throat while he was sleeping with a switchblade provided by It.
Upon returning to home from the sewers, Henry was eventually convicted for Butch's murder (as well as the rest of the killings that occurred throughout the summer), and had been arrested by the cops, who had been waiting for him.
