One of the most essential elements of Peaky Blinders, both in terms of the badassery the show exudes and in terms of furthering the narrative of the seasons and the characters, is violence. Violence is a crucial aspect of the show, from razor gang antics to assassination attempts, and many great quotes from Tommy Shelby and his supporting cast speak about it.

The show has so many memorable and iconic lines, and a good number of them have something to do with this violence, from planning assaults to talking about violent people to teaching valuable lessons to others.

Tommy's Method Of Getting Suits

"I Don't Pay For Suits. My Suits Are On The House Or The House Burns Down."

The Shelby brothers invade a London night club in Peaky Blinders

The outfits of the Peaky Blinders have become pretty iconic, with the razor-clad flat caps and expensive suits becoming synonymous with the Birmingham-based gang.

This quote from Tommy lets fans know that while the Blinders do make looking the part a priority, they do not pay for their suits, with the threat of violence looming over anyone who would deny them, indicative of how fear and violence are important tools for the gang.

Alfie's Lesson To His New Workers

"He'll Wake Up. Granted, He Won't Have Any Teeth Left, But He Will Be A Wiser Man For It."

Alfie threatens one of Tommy’s worker after he makes a joke that gets his friend beat up in Peaky Blinders

Alfie Solomons is undoubtedly one of Peaky Blinders' best and most unhinged characters, played brilliantly by Tom Hardy. This quote from him gets directed at one of his new factory workers and firmly establishes his toughness as a leader.

It is another quote that sees violence used as a tool to motivate and inspire fear. Alfie breaks the face of one worker due to the joke of another, keeping both in line as a result. It is cruel but intelligent, which pretty much sums Alfie up.

Arthur's Opinion On Going To Heaven

"Who Wants To Be In Heaven When You Can Be Sending Men To F***ing Hell."

Arthur Shelby smokes a cigar as a he dares a woman to shoot him in Peaky Blinders

Arthur Shelby has a relationship with God that sees him speak about being a good man and having the potential to get to heaven, but ultimately admitting he will be going to hell, saying at one point that his hands "belong to the devil."

This quote from the older Shelby brother comes relatively early in the show and sees him pretty much revel in the pain that he causes others. He enjoys violence and thrives on it, liking it better than the prospect of getting to heaven at all.

All It Takes For Tommy's Wrath

"I Just Put A Bullet In His Head. He Looked At Me The Wrong Way."

Tommy Shelby drinking gin in Peaky Blinders

The Peaky Blinders were much more openly violent and reckless before legitimate business became the priority. Since then, Tommy tends to avoid stuff like shooting people in the head on the regular, but before then, anything could trigger him.

As he states here, merely looking at him the wrong way was enough for Tommy to kill someone. His cold-heartedness, lack of remorse, and serious violence-related issues shine through in this quote that fans have well remembered.

Tommy's Tactics & Ruthlessness

"You Strike When Your Enemy Is Weak."

Tommy tells the rest of the Shelby family they will be going to jail in Peaky Blinders

Tommy's mind is like a machine that is always ticking along, and the gears are constantly in motion as he plans two steps ahead. His tactical intelligence is one of his most impressive traits. This line is indicative of one of his many simple philosophies.

Tommy has shown himself unafraid to face off with enemies on an even playing field with him or even those who have the upper hand. But, his ruthless temperament and sheer will, mean he encourages striking against weakened enemies with all his force.

The Advantage Of More Violent Men

"In All The World Violent Men Are The Easiest To Deal With."

Tommy captured by the IRA in Peaky Blinders

Irene O'Donnell is a member of the IRA in Peaky Blinders and one of the two members who capture Tommy and talk to him in a conversation that has this memorable line.

The women of Peaky Blinders so often prove themselves as strong, fierce, and intelligent individuals able to handle the recklessness and violence of the men. Violent men, including Tommy, often think with their anger, and O'Donnell's quote shows Tommy she is not afraid of him or the threats he poses to her.

Peace Via Violence

"The Only Way To Guarantee Peace Is To Make The Prospect Of War Seem Hopeless."

Tommy frowning and looking confused in Peaky Blinders

When John gets on the bad side of the Changretta's, refusing to apologize or compromise as recommended by Arthur and Polly, Tommy applauds his younger brother, demanding that they further insult them, using violence to do so.

He demands they take their pubs and not take their heels off their necks. He believes the only way to prevent an all-out war is by striking so fast and so viciously that a war on their part seems hopeless, that peace is their only option. Striking enemies into submission and imposing his will on them in a brutal fashion is something Tommy does time and time again in the series.

Alfie's Own Version Of Stigmata

"It Was F***ing Biblical, Mate."

Alfie Solomons and Tommy Shelby talk about Alfie's war with Sabini and ways to win it in Peaky Blinders

Alfie has so many memorable one-liners in Peaky Blinders, having so many of the show's most iconic quotes, including this one in which he talks about the violence he inflicted on an Italian.

He says that he once inflicted his own form of stigmata, detailing that he held the man's face to a trench, shoved a nail up his nose, and hammered it up. It is a harrowing description of Alfie's violent tendencies that becomes pretty hilarious with this one line.

Tommy's Demands

"No Fighting. No F***ing Fighting. No Fighting. No F***ing Fighting!"

Tommy Shelby warns the Peaky Blinders not to fight at his wedding

One of the funniest and most memorable scenes in Peaky Blinders comes when Tommy speaks to other members of the Peaky Blinders before the wedding of Tommy and Grace, demanding they be on their best behavior.

The line and sequence, in general, are fondly remembered by all fans of the show, especially since right after making this simple demand to the rest of them, he violently shoves one of the waiters of the wedding. He may care about Grace and her wishes, but he still has a short fuse.

Alfie Calls Out Tommy's Hypocrisy

"How Many Fathers, Right, How Many Sons, Yeah, Have You Cut, Killed, Mamed, Butchered, Innocent and Guilty, To Send Straight To F***ing Hell, Just Like Me!"

Tommy and Alfie fight about Alfie's role in Tommy's son being kidnapped by Father Hughes in Peaky Blinders

There are a handful of scenes considered the best in the five seasons of Peaky Blinders, including this one where Tommy confronts Alfie for his betrayal, and Alfie calls Tommy out for his hypocrisy.

This line from Alfie's monologue sees Alfie admit to the many atrocities he has performed over his life all while almost demanding Tommy admit the same to himself. It is an excellent insight into both characters' minds and a frightening realization that they are not good people; they are intensely violent men.
