"Really? Cause I don't want anyone to die either. Exactly why I want to kill that thing. I'm not gonna keep hiding like a coward and watching innocent lives be taken. I'd rather die if it means others survive."
"Ok and without it well then you're just a coward, you become selfish and a complete asshole. It's not trusting that something will work 100% it's just accepting the chance that it will work as a possibility. That possibility is what makes anything worth trying. But if you'd rather be a selfish coward, watching people die from the side-lines and moving on like it's nothing, fine by me, If you don't mind I have a monster to either kill or die trying."
