Complete Monster/Ripper Street

The streets of London are filled with many dangerous criminals but here are the worst of them all


 * Sir Arthur Donaldson, from the series premiere of Ripper Street, "I Need Light", first shows up mere months after Jack's rampage, yet manages to be a depraved monster in his own right. He was a serial rapist who abducted women by drugging them, then he would take them to a secret location where he would rape them before strangling them to death. Next, to remove suspicion from himself, he would mutilate them so they would appear to be new victims of Jack. His monstrous nature also extends to his lone servant, whom he would force to film him commit his atrocities all so he could watch them in his spare time. The abuse that Donaldson gave to his servant was so bad that the servant eventually killed himself. In the end, while Donaldson was only the first felon Detective Inspector Edmund Reid encountered since his search for The Ripper, it was this case that convinces Reid to let go of his pursuit, so he can find other criminals lurking in the streets of Whitechapel.
 * Sir Victor Silver, from season 1's finale "What Use Our Work?", may look like a gentleman but in truth he is anything but. Long ago, he was suspected of being Jack, but the issue was dropped when he thought to have died in a boat accident. However, he managed to survive, and continued his business in kidnapping women and having them shipped to South America as Sex Slaves, using his superficial charm to gain their trust before luring them to his family's estate, where he would shackle them to a bed for days before drugging them and locking them in small boxes to be sent overseas. Overall, while only just one of many Ripper suspects, he came closest to matching The Ripper's description that he might as well be the Serial Killer himself.
 * Detective Inspector Jedediah Shine of Division K is the Big Bad of season 2 as well as the Arch Enemy and Evil Counterpart of Edmund Reid. First appearing in the seasson premier "Pure as the Driven", he had a girl he brought with him from Hong Kong to run his heroin ring and be his lover, only to abandon her once Reid arrests her and dismantles the ring. He also visits a sergeant of his in a hospital who was injured earlier in this episode, so he could kill him to make sure he won't say anything. In the next episode, "Am I Not Monstrous?", Shine finds out a patient, Joseph "Elephant Man" Merrick, saw what he did and prepared to testify against him, so Shine kills him too, all while making it look like he dies from his deformities. He later appears in the two-parter "Our Betrayal", where it is revealed that he blackmailed to join Reid's division to serve as The Mole for him. He later strangles to death an innocent jewelry store owner he knows in front of flight just to assert his power over him. He later burns a house down, along with killing a family—including a child—inside it, where it is also revealed that  with this being far from the only one; . Corrupt to the core, Jedediah Shine is everything Reid is striving to get rid of in Whitechapel.
 * Dr. Charles Broadwick, from season 2's "Dynamite and a Woman", despite knowing how unstable and dangerous direct current is compared to alternating current, wants to have the entire city of London use the former, just so he could profit off of it, completely uncaring how many people could get killed because of these currents. In an effort to hide the truth from the public, he frees Aiden Galvin, while killing the police officer transporting him. He then has Galvin plant a bomb at one of his colleague's room, then frame the Irish Republican Brotherhood for this. Once this succeeds, Broadwick send him to place a bomb at Whitechapel University, where all of his colleagues will be in one place for him to kill. It was also revealed that this was not only time Broadwick collaborated with Galvin, as he did so a couple years ago where he had 12 innocent people killed, then pins all the blame on his cohort, while he walks free. While Galvin has a daughter whom he genuinely cares for, Broadwick has no such qualities, and is solely defined by his Greed, which he has killed many to satisfy and would kill many more.
 * Gabriel Cain, from season 2's "A Stronger Loving World", was a member of the Hermetic Order of the Golden Dawn, before he was kicked out for his radical beliefs that the world is corrupt. He then formed a cult solely based around his ideology. He brainwashes all of his followers to carry out suicide attacks all to spite those whom he believed had wronged him. These tactics included having one of them to burn himself alive in a Catholic Church full of innocents, framing the Hebrews of Whitechapel for it; to having another slit his own throat in front of the detectives investigating him. He also has his daughter, Bella, marry Detective Inspector Drake Bennet, so that he could recruit him into the cult in the near future. When Drake discovers the cult as well as the revelation that Cain had manipulated Bella, his own daughter, into have sex with him to impregnate her with his child, Cain captures him and attempts to have him as well all of his followers—including Bella—die by drinking poisoned wine as a way to Destroy the Evidence against him, at which point he could form another cult in hiding. Ultimately, his depraved acts prove that Cain himself is just as morally corrupt, if not more so, as the world he is claiming to be fighting against.
