As an empath, my first straight up answer was no. Everyone's first answer is usually no actually. But a few people's answer change as they give it some thought. I did too. My answer changed too.

I would kill someone to save someone. But that too on some conditions. I would never kill anyone if the person to be saved is unknown to me. I would never. But then if the person is known to me or close to me, I will definitely kill anyone to save them.

Another condition arrives at this point. What if the person I have to kill is close to me too? Well in that case of both people, the one I have to save and the one I have to kill, being close to me, I will undoubtedly go for the first thing that comes in my mind.

That is, to kill myself.

Without a doubt, I'd choose that.
