Frank Murphy (Bill Burr) is a loyal but problematic family man. While he attempts to work in the best interests of his wife and children his rage tends to get the best of him and he instinctively lashes out at them and the world.
No one would blame Frank for being an imperfect parent. However, he has consistently made mistakes that have jeopardized his and his family's well-being. The errors below mark some of the worst things he has committed during the series' run. These are in no particular order.
Indirectly Caused Kevin to Drown
Early on in the series, it was implied Kevin (Galaxy Quest)is mentally impaired which causes him to struggle in school. It was later revealed this was caused by a drowning incident at a motel pool. As a toddler, he was under an oblivious and intoxicated Frank's supervision when his stroller rolled into the pool. Kevin pleaded to his dad but ended up drowning and went two minutes without oxygen. As a result, Kevin developed PTSD and other problems. Despite Frank feeling awful about it, the situation could have been prevented if he was more cautious.
Not Telling Sue About the Promotion
In season one, some of Frank's proudest achievements is being the man of the family and breadwinner. However, when Sue (Mo Collins from Mad TV) calls to offer her a promotion but Frank answers and says Sue was not interested. She later found out and this caused a dispute between the two until she was assured by Frank it was okay.
Abusing His Family
As previously stated, Frank has had a recurring problem of lashing out at his family. While it is mostly verbal, he has repeatedly hit Kevin and Bill (Breaking Bad) was emotionally and physically abusive to him. And while it explained Frank's behavior it does not obviously excuse his actions.
Discouraging His Children's Interests
While Frank has gradually improved in this department he has discouraged his children's hobbies and ions.
Examples include Kevin's desire to be a musician but Frank dismissed it as unethical and wishy-washy. Meanwhile, Maureen (Debi Derryberry from Jimmy Neutron: Boy Genius) initially pressed her parents to let her the computer club but Frank felt it was unladylike. Later on, Frank would overturn his opinions and later encouraged Kevin to pursue his dream (while he promised to improve in school) and let Maureen the computer club.
Beating Up His Father
Big Bill was introduced in season four. Initially appearing as a reformed version of his former self. Frank was infuriated by this and insisted it was a facade. However, they started getting along and became closer throughout the season. On the night of Maureen's play, all seemed well until they got drunk and ended up in a fight. While Bill provoked Frank the latter decided to whale on him in front of the audience and Maureen, embarrassing her. It can be argued over whether Bill deserved it, but inevitably Frank did the same thing to Maureen that his father did to him many years ago.
Traveling Out of Town Before Sue Gives Birth
Tensions were running high in the remaining days of Sue's pregnancy. Yet, the final straw was when Frank struck his father at Maureen's play. This erupts into a huge argument. Afterward, he decides to Bob and the other Mohican employees on a work trip to Cleveland despite Sue being due soon. He reasoned that he knew where he was truly needed. Despite this being decided in the heat of the moment Frank should have stayed. Fortunately, despite Sue going into labor, he was able to make it in time for the delivery.
Being Hard on Kevin
While Frank and Kevin were close in his early years they would become distant later on. Out of his children, Frank tends to pick on Kevin the most. He perceives his son's oafishness and disregard for school and authority as disrespect and laziness but it is much deeper than that. Sue insists Frank be gentler but it takes some time before he realizes the ramifications of his actions. He has since attempted to make up for this and be more considerate.
Breaking Promises
Not every promise can be kept but Frank has let one too many loose. As a result of his poor planning, negligence, or forgetfulness he has caused his family and friend to hang to dry.
Whether it was promising to bring his son to tryouts or hockey practice or promising he would always his wife's endeavors they have inevitably fallen through. This has caused them to occasionally lack faith and trust in Frank.
Buying TV
In the first episode of the series, Frank decides to upgrade his rinky-dink TV for the latest model in time for the big sports game. And he can invite the neighborhood for a watch party. This would eventually set the family back financially and put them further into debt. This being further complicated when Frank was fired. While this was one of the least bad things Frank has done he mostly bought the TV to rub it in his neighbor Vic (Sam Rockwell from Moon)'s face.
Putting Work Before Family
This is more understandable because of the family's poor financial standing. Frank was determined to make sure his family is taken care of. And as manager of Mohican Airways, a lot was riding on his shoulders. However, he has let work get in the way of family priorities. And this is for a company where despite some of his co-workers including Rosie (Christmas Eve. Despite Frank's prior mistakes, he is still determined to amend himself. And with season five on the rise audiences just may see a reformed Frank Murphy.
