Incestuous historicizing

Given the rumors about Woody's dad, convicted hit man Charles Harrelson who some accused of having been on the knoll when JFK was killed (which he admitted when drunk, but denied when sober) isn't a bit weird to have the son in the role of LBJ -- a man who arguably also had a role in Kennedy's death?

I mean, none of that is Woody's fault, of course. But doesn't that make it a tad uncomfortable?

Or are the daddies, Charles and Lyndon, just never guilty?
