Hurting his son
On 10 May 1982, Mary Anne died giving birth to their son, John Constantine. This caused Tommy to deeply resent John, blaming him for Mary Anne's death and calling him "Killer" his whole life. Additionally, whenever Tommy came home from drinking at the bar, he would hit John in the face and remind him his mother died because of him. Tommy also smoked a lot and would put out his cigarettes by burning them on John's arms to punish his son.
Tommy died sometime in or before 2018.
