I can't say I didn't take a few people out like that. I got pretty brutal as a vampire. Sorry that happened though. Sounded like she cheated in a way. What kind of tournament was this?
For me, I traded my immortal life for a human one. I'd lived long enough, and the losses were too much, and I wanted my girl to have chances that immortals don't have, like a normal husband, kids, etc. I died of old age at the end.
