When someone believes violence is the answer and soon enough, they join the dark side , or karma gets to them.
That person, like Light Yagami, believes that by killing/hurting those people will make society a better place. They also believe that getting rid of all bad people will make the Earth pure.
"Billy wants to kill all the bullies in the school. Damn, he finna go Kira.
"I finna go Kira on my Math Teacher if they don't let me skip class."
"GOD DAMN I GOTTA GO TO THE BATHROOM! IF THE TEACHER DOESN'T LET ME GO, I FINNA GO KIRA ON HIM!"
Get the Kira mug.
