So tell me I'm not the only one who thinks it likely that Jack Murdock's father was abusive. Mrs. Murdock, heartsick at her failure to make her son a better man (his whole job consists of beating people up, after all), bitterly tells her grandson that Murdock men have "a devil" in them, after all. Jack's just as eager to get his son to escape this cycle of violence, and just as doomed.

That's my headcanon, anyhow. (And about the only thing that excuses that horrible line about Murdock men having a devil in them, although it's still terrible theology.) Y/N? Other thoughts?
