Yup.
Mutations don't erase emotions. The witchers are training to avoid emotions as an auto-defense way: don't have any relation with normal humans because they will be always rejected. They are not psychopaths with atrophied frontal lobes, but humans trained to control and override emotions.
Anyway I don't know where I read (here in the forum for sure but don't remember where) that witchers of The Cat school were a bit crazy...
