#somebody in the tags asked for it and I felt obliged as Junko's submitter

[silwer999]

Written from memory list of some things Junko did to spread suffering and pain: 

Emotionally abused her sister for their entire life

Led to the death of Hope's Peak's Student council

Convinced the class 77B to become her minions, which later led them to kill their friends and families, commit acts of self-harm and do other atrocities in the name of her ideology

Killed her own boyfriend 

Led to the mass suicide of the school reserve course

Started off the worldwide riots, wars and mass murders that left the world almost completely destroyed

Convinced a group of kids of her ideology which led them to brainwash other children and conduct mass murders of adults

Killed Hope's Peak's principal in painful execution

Memory wiped her classmates who were being protected in modified Hope's Peak so that they would not know about the state of the world and try to escape their supposed entrapment

Force those classmates into taking part in a killing game to escape the school

Killed her own sister

Kidnapped her classmates, friends and families so she could further blackmail them into going along with the killing game

Thretheend to spread their secrets to blackmail them further

Killed several students in gruesome painful executions

Stole a suicide note one of her classmates left and switched it for a fake one to make the suffering and grief of the victim's best friend worse, which almost led to the death of other remaining students

Smashed to pieces the AI that the other students relied on to escape, it was heavily implied that the AI could feel pain

Desecrated her sister's corpse

Set up a false murder so she could implicate the student most threatening to her

Left the body of Hope's Peak's principal on display for his daughter to find

Attempted to break the spirit of the remaining students so that they would agree to kill her hopeful opponent

Put herself through gruesome painful execution

Saved her personality as an AI so she could spread despair even after death

With the help of her coconspirator infected the peaceful virtual world that was meant to rehabilitate her minions to turn it into another killing game

Killed several of her ex-minions in even more gruesome painful executions, including manipulating one of them to accidentally seriously hurt her closest person right before dying

Infected several of the game participants with a plague that would last till somebody was killed

Starved the game participants to get them to kill somebody

Tried to manipulate the surviving game participants to let her infect the bodies of their fallen comrades so that she could live again to spread despair

Junko Enoshima (Danganronpa) "Junko loves nothing more than destroying hope and bringing pain and suffering to all(even herself). This is literally the only thing that makes her happy. She loves destruction so much that she ruined the world just so she could watch everybody suffer. She also started a cult of sorts(a very Desolation-like move) filled with people she brainwashed and used them for her goals. Important to note is where Junko starts off her carnage and her favourite victims as Desolation is also the destruction of potential. Junko attended Hope's Peak Academy, the most potential-filled place in Danganronpa's universe. Hope's Peak Academy is a school that only accepts those with exceptional talent, i.e. the most potential, and this is the place where Junko starts her reign of terror. She turned one class of hopefuls into her aforementioned cult, led to the mass suicide of reserve course students and started the end of the world from there. Later she forced her own class out of what was supposed to be a shelter for the future into a killing game where she psychologically tortured and killed them, broadcasting the carnage to kill hope in the hearts of what was left of the world."

Shabriri (Elden Ring) ""The most reviled man in all history" of the Lands Between, who has been serving the Frenzied Flame by preaching chaos and destruction long enough that "It is said that the sickness of the flame of frenzy began with [him]." According to the Talisman called Shabriri’s Woe, “It is said that […] Shabriri, had his eyes gouged out as punishment for the crime of slander, and, with time, the blight of the flame of frenzy came to dwell in the empty sockets.” He encourages the Tarnished to shirk the role of Elden Lord and instead become the Lord of Frenzied Flame. While at first he paints it as a more "noble" means of attaining Lordship (since it doesn’t require killing your companion Melina), he makes no effort to lie about the fact that becoming the Lord of Frenzied Flame will burn the world and everything within it--in fact, he's rather vocal about his excitement at the idea of Chaos taking the world. The Frenzied Flame is an outer god associated of madness, destruction, flame, chaos, and the end of life, which seeks to create a Lord of Chaos through the Three Fingers. It is drawn to people who succumb to despair and grief--it was summoned into the Lands Between by the dying wish of the genocided nomads, it infects Edgar after his daughter Irina dies, and soldiers on Mt. Gelmir (site of the most horrific battle of the Shattering) use Frenzied Flame Incantations. Hyetta (who might be Irina) set out to become a Finger Maiden to the Three Fingers by consuming “Shabriri Grapes”--shriveled, oozing eyeballs apparently infected with the Frenzied Flame. She claims that the Frenzied Flame despises the Greater Will for fragmenting an ancient source of life, the "One Great," to create the lesser forms of life that populate the Lands Between; the Frenzied Flame would see the One Great restored, which necessitates the eradication of all forms of life and the scorching of the entire world by the fires of the Frenzied Flame. So feared and reviled is the Frenzied Flame and its goal of universal destruction that even the adherents of other gods, themselves mortal enemies, teamed up to curb its influence. If the Tarnished follows Shabriri’s advice and inherits the Frenzied Flame, they'll become the Lord of Chaos who will burn the Elden Ring, the Erdtree and likely all life, which is basically a successful Desolation Ritual à la “The Scoured Earth”."
