5.Kira Would Not Be Happy About Letting A Mass Murderer Like Frieza Live
There are many powerful villains in Dragon Ball that kill a lot of people (and aliens). The most popular is arguably Frieza, who would go so far as to destroy the Earth and other planets. If Kira was in the same universe, he wouldn't be happy about a mass murderer trying to destroy everything that he had worked for.
While Goku and the other heroes of the series fight against Frieza, Kira would simply write his name down and wait 40 seconds. But there are many other characters in the anime that Kira would kill.
4.Kira Would Take Down Beerus In Order To Secure More Worshipers For Himself
Beerus is another character from Dragon Ball that would die if Kira knew about him. However, unlike Frieza, Kira actually has two reasons to end his life. Due to wanting to be a god, Kira would be glad to kill the God of Destruction in hopes that more people would worship him.
Many characters in the franchise are terrified of Beerus, knowing that he could kill them at any moment. Kira would probably see Berrus as a terrorist so he'd end his life as quickly as possible, even if he wasn't a god.
3.Kira Would Not Show Eren Mercy After The Marley Attack
Eren is the main character of Attack on Titan and has recently become the antagonist of the series. Throughout most of the anime, Kira would probably want Eren to live as he gave Paradis hopes.
However, now that he attacked Marley without a second thought, causing many innocent people to die, Kira would no longer see the good in him. Despite how similar the two actually are, being both the main character and villain of their series, the two would not get along.
2.Kira Would Take Down Akihiko Kayaba In Order To Prevent Akihiko From Beating Him
Like Kira, Akihiko Kayaba, the main antagonist of Sword Art Online, wanted to make a new world. He created the video game that the series is named after and trapped all of its players inside of it. The only way for them to be free was to beat the game, but if they were defeated, they'd die in the real world as well.
Kira could never allow someone to beat him and take everything that he wanted so he'd kill Akihiko Kayaba, and possibly even try to save the game's players so they would worship him.
1.Kira Would Not Tolerate The Lives Father Had Taken
The main antagonist of Fullmetal Alchemist is most notably known as Father. Like Kira and Akihiko Kayaba, he wanted to have the power of a god, as well as learn as much about the world as he could. In order to do so, he killed many people, created the Homunculi, and removed sin from himself, causing him to always be calm, serious, and even more menacing.
Though he may not have seen anything wrong in what he had done, Kira wouldn't agree with him and think he was a sinner.
