SJSinNYC:
That’s exactly my point. My answer to both questions (marry someone who has a significant chance of dying and someone who is doing something assur but willing to try to work on it) is yes, in certain cases. I adressed both of your points in my original post:
1: The man will not smoke near his spouse or children (second hand smoke, let alone pregnancy)
2: Sometime people marry those with known risks. We are talking about the woman who is (due to the shidduch crisis or other issues) at that point.
