I will avoid having all characters killed off my first play through. Even if that means resetting the game. I was more than prepared to do so in Heavy Rain but I was so focused on not dying my first play through that I actually went through the game without anyone taking a dirt nap.
I'm more careless my second playthrough just to see how things play out. And I usually make junction saving points when I want to explore different stories.
That said I have no interest in Until Dawn. Just sharing my two cents.
