My Revenge is Your End

What wrong thing did you do? Why did I suddenly pulled the trigger? Sirens? Who called the police? You can't be arrested... And so do I. But why? Why did I killed you, why?! Is it because you're a killer? Now, I can't stay any longer. I don't want to live in jail. Even if I need to cling to life I will. If they are right. If it's true that you're a killer then I know that I just did the right thing. I won't come with them. What I would do, is not to regret that I killed you.
