In Titanic (1997), Rose says that people on the lifeboats would have to "wait for an absolution which would never come." I know she was saying that more because they didn't come back for people still in the water.
But at the same time, she did take a seat on a lifeboat, which she got off as it was being lowered, but it was too late to have someone take her place. So she too took a seat that one or more could have taken.
How she would have acted on a lifeboat is another question, though when Margaret "Molly" Brown protested that they should go get survivors, she was threatened to be thrown off the boat.
So I'm not sure if Rose's comment would apply to her. So did Rose think her actions didn't warrant any guilt?
