There is nothing in legend, or in the show, that says that Excalibur can only be pulled by a person with the purest heart. The legendary sword in the stone could only be pulled by the person that is the rightful King of England. Which was Arthur, who was the son of the former king and sent into hiding when the kingdom fell.

Now, for the purposes of Once, I think that Arthur THOUGHT it was all about being King, and maybe it was. But I think that there will be a different set of circumstances for the next weilder of Excalibur.
