If I'm not mistaken, all questions that do a variable amount of damage are based one of your character's attributes. It is likely that in this case your particular attribute isn't very high, and you were killed instead of merely damaged. Notice that some characters take no damage at all, meaning their stat was sufficiently high to avoid all of it.
There are bunches of quesions that share this attribute-dependent nature in this game. Frankly, I'm quite surprised you haven't posted this question far earlier than mission 39.
As far as the data on my site goes, feel free to edit the question on the site when your experience differs from that shown. Any piece of accurate information is worth adding to help others.
