I agree that the things Blackbeard did were pretty ruthless but for me and from what it seems others as well, the way in which he did those things, the acting didn't portray him as such a bad ass.
As for Davy Jones, it was either serve or die instantly, not serve or go on your merry way.
As for age, Bill Nighy is just a few years younger than Ian McShane. And to be honest but not disrespectful in any way, it's really not our, the movie goer's job to empathize with the actor but with who they are portraying. Ok he's 70years old in real life but in the movie do we know how old he is (I don't recall them saying)? I don't know how old Anythiny Hopkins is but he's still throwing out some great performances at his age. He was fantastic as Odin.
