Do you know personally some CEO-s? I know a couple and they generally seem less empathic than the general population, so I don't think that like/dislike even applies.
On the other hand, trying to do something "new" is lots of headaches, so emotions are not always a plus. I could make a parallel to doctors: you don't want a doctor to start crying in a middle of an operation because he feels bad for you, but you can't let doctors doing everything that they want - there needs to be some checks on them.
I would say that the parallel is not at all accurate because the relationship between a doctor and a patient undergoing surgery is not the same as the one you and I have with CEOs. And a lot of good doctors have emotions and they use them to influence patient outcomes positively.
