I first went into this thinking it was indirect (as most of these are) and started reading and I was just downright horrified at the stuff he did to her. And then with the kerosene? And the knife? I think you did the most appropriate thing at the time, he was too violent to subdue, and he would’ve killed her, you, and possibly everyone on the flat had you waited any longer. I would have done the same had I been in your shoes, and I’m glad she turned out alright. Thank you for helping this poor girl. You not only cared, but had the will to act. I don’t think killing is the way to solve anything, but he was going to kill her, it was the right thing to do.
