I'd cast the curse.

Curse: You have the ability to alter the past in any way you want with the ability to see the repercussions of each alteration you make. In addition, you are able to travel to the past and back to the time you came from before going to the past (for example, I could start in 2017, travel to 1945, then return to 2017) so you can alter the past in person.

Price: Since you have the ability to see the repercussions of every alteration you make to the timeline, you also see the repercussions of every action you make, as it becomes the past and thus it was altered by your actions, even if it was in that time's present. As a result, you see so many time streams that you need to control your abilities or else the knowledge of all the possible futures will kill you.

Summary: You can change the past and travel back to the present, knowing the possible repercussions of each alteration you make, but the knowledge of all the possible futures you could create can kill you unless you control it.
