You should get the thought "What have I done..." and should level it to "This is what needs to be done."
But you first initially unlock "What have I done..." from progressing the "Pink" interactions that appear when talking to Sheila at the livingroom and at the kitchen.
You probably didn't finish something there.
(These are the thought levels:
+"This is what needs to be done.."
+"I have no other option"
"I have done something wrong...."
-"What have I done..."
- "I am a sinner!"
