I need your opinion

You are in a dystopian fantasy world, getting hunted by a woman who killed your parents.

Somehow, you knocked her unconscious together with your partner (who also btw was tortured by woman) while fighting her.

That woman is the reason for your suffering, both past and the coming future. And you know this.

Do you kill her or not kill her and move on with escape plans? (Don't worry about time, you have few minutes to spare to do the deed)

Also tell me the reason why you chose either option.

P.S. Would your decision change if you were 17, and that woman was your 20-year-old partner’s mother, someone who hated him from birth and was out to kill him whenever she got the chance?
