You can kill Jack three times.
- In the cemetary in Aleroth.
- In the cellar of an empty house in Aleroth.
- In the cemetary in the poor quarters.

But if you kill him first in the cemetary in the poor quarters it becomes impossible to kill him in Aleroth.
So you have to respect the order if you really want to kill him three times and get the XP points.
