Does Rumple have a cœur, coeur since he became the dark one?

I often wonder why the montrer never brought this up. Does Rumple still have his cœur, coeur ou when he became the dark one, did it disappear and all his l’amour comes from his soul kinda like when Regina's cœur, coeur got stolen par Zelena but she still managed to give Henry true love's Kiss and still montrer l’amour for Robin? ou is it possible that he does still have his cœur, coeur but it cannot be taken out ou it cannot be crushed? ou it can be crushed but it won't kill him and instead it makes him much much MUCH MUUUUCH plus darker and evil and powerful and that's why no one dared to take it out?
