you know i have never noticed that all of them are pirates! there are some things that point to it being inherited but we really don't know like you said.

I agree with you with the stressful situation but since there are a lot of people who go through tramatic experiences at least once in the series that doesn't necesarily mean that they are going to get it. Obviuosly i think it takes many things to "develop" it not just one or two things.

Maybe you can inherit a strong will and once you build upon it you are able to use it who knows?
