I want to get a tattoo so I want to be absolutely sure :).
I would say Veux-tu mourir avec des regrets ?, using a shorter construction than Est-ce que tu veux mourir avec des regrets.
Please note that the negative form without regrets is more commonly used in French, since sans regret is easier to say than avec des regrets.
Personnally Mourir sans regret (Die without regrets) would be my best option.
If you do decide to go with an affirmative statement (which I think you should) instead of a question, I would change 'mourir' to 'vivre' (one less letter and, in my opinion, a bit more positive)="Vivre sans regrets"
