[Feel the need to point out that Blaire doesn't actually know that she killed that group of people. She wasn't watching them or trying to use her power or anything. And she didn't kill any of the ones who showed up after that (she cut their weapons and hands up).]
Dozens? I think to myself. If you count the man today and the two who attacked me the total is only three. No… there were 3 more who died because of me. 'They' were alive. As much as I want to say they weren't.
"It's my fault…" I fall to my knees. "So that's it. Even if I didn't know they were there, even if I was defending myself, when that man shot and missed because his hands were trembling with fear. When he hit the things… people behind me. That was my fault, right? I killed them, right? That's what you're saying… right?" I pause for a moment. "You're right. You're right you're right you're right! If I hadn't understood that, I wouldn't have killed him. I wouldn't have been angry. Even if it was self defense, I would have let him live if I hadn't killed them."
[I wanted to reveal this stuff later, but guess I'll have to do it now. If you didn't get it, the whole spiel Blaire gave was her coming to terms with a past event. She was in a situation being threatened at gunpoint by someone, so she tried to retaliate, but three people behind her got shot because the gunman was startled. When the people were shot, she became angry with the gunman, and killed him, then started to think that she caused the people's deaths. To cope with this she started viewing people she doesn't know as inanimate objects. She viewed the enemies before as training dummies, because she understood that they needed to be killed, and therefore assigned them a role as an inanimate object that she would attack.]
I compose myself.
"I won't kill people through inaction, and I'll only act to kill those who threaten me or others I want to help. That's what I decided on. I don't care if the way I do things pisses people off, they can go f*ck themselves as long as they're alive."
