Individual human behaviour is full of little seeming hypocrisies and counter intuitiveness when looked at from the outside. There's usually some explanation that makes sense to the individual themselves or a blind spot they're in denial about or don't realise they have.
A lot of human behaviour is learned and becomes habitualised rather than logically thought through. Habits are sub-conscious and therefore logic doesn't (as) often get applied.
They may be more likely to have the capacity, but no way it's amy kind of guarantee.
