I ruined 9 people's lives for nothing
Why did you ruin nine people's lives?
I don't know why I did that. I felt like doing it just for fun.
What you did was unacceptable. There is no reason to intentionally ruin the lives of anyone. That is morally wrong.
I don't really want to hear that shit. You are just mad at me now.
You need to go to those people and try to remedy their situations. Nobody deserves to have their lives ruined. What if someone had done that to you?
