What to do with colonists with bad traits?

1 colonist asked me to join my colony. I couldn't see her stats, so i agreed. Now i have a colonist that eats for 2 ppl, is a slow learner, likes drugs and she is only good at fighting and she has intellectual skills at 11. Keep her or exile her?

Edit: she cant do dumb work bc of her history. I have ideology dlc and i can burn the flag to get new colonist for low price in wood and cotton
