If it was my dad, i would. if it were my mom, no.
I'd find it very hard to resist if they tried killing me. Animal instincts would overrule rational judgement.
I don't know my parents, so for me, it would be just as if anyone ells attacked me. If any of my other sets of parents, tried to kill me, the yes still I would fight back with every thing I have.
If I was in immediate danger: I'm pretty sure I could take both of them in a fight, and I'd simply find a way to subdue them if I could. But if they were both trying (which is impossible because my father is already dead), or they had weapons, I might have to resort to lethal force.
If they attacked me, I might kill them in self defense, but not in cold blood.
I don't believe an eye for an eye would solve it, I believe you can understand why they did it and overcome this situation.
I'd report them and let law enforcement deal with it. (It's not like my parents would ever do something that stupid) However if I couldn't defend myself without killing them during their murder attempt, i'd probably have to kill them.
I would try to detain them. I would only kill them as a last resort.
I'd definitely incapacitate them, but it would take a LOT for me to kill my parents.
I would run like hell but I wouldn't kill them on if I really had to yes
I could outrun both my parents with ease.
