Jolly Roger's Powers

[Ben Lockshot]

So In the story Of Jolly Roger it said that he became Undead because. Roger Wanted to be a Pirate Lord so he chalenged Jack to a Poker match. And he got a Witch Doctor to give him magic cards but he still lost against Jack. So he went and Killed the Witch Doctor but right before he did the Hitch Doctor Cursed him.

But my Question is that if Jolly was cursed why would he be given these Powers? Or how did he get the Powers? What you you guys think?
