From the guide (as I couldn't figure out why she kept going with her dad):

Recruit Carys: she will go with her dad if your corruption flags are 2 or more. A flag is gained by each companion with 5+ CP or if the player has morality below 5, if the morality 5 or more a flag decrease instead.

So, it's not just your corruption. I used a cheat to put everyone's morality to 100 and Carys did not go with her father this time and now has, finally, joined.
