Would you kill to Survive ?

When I saw this title it made me think of the movie series Saw. What would you do to survive type of deal. It all depends on who I'd have to kill, what point I am in my life, and what the circumstances were. Like if I were a 90 year old and I had to kill a small child to live, no I wouldn't, I lived my life, that's a poor child there that hasn't had a chance yet. Like I said it's all in the circumstances of the situation.

I will not do that if I don't have to, as long as I see others well behave and doesn't deserved to be killed I maybe cruel but I still have a heart to give mercy unless I must kill with a good reason and with my final decision I will

I could kill to survive, but as much as possible, I wouldn't. I really don't like the idea of killing other people just to survive. I have principles and I wouldn't want to go against them just for survival. But if my loved one's lives are compromised, then I would definitely kill anyone just to ensure their survival.
