Übersetzung - Griechisch-Englisch - "Επίσης έχεις τελειώσει γιατί είσαι γαϊδούρι, όπως όλες σας"

Lit: "You have finished too, because you are a donkey just like the rest of you" (adressed to a woman, "rest donkeys"-rest women).

donkey= stubborn, insensitive, unaffected by other's needs and emotions, egocentric person.

I think here is used more in the meaning of "insensitive/unaffected".

Could be, even though, usually the word donkey it is associated with stubbornness; there is a Greek expression "ένας γάιδαρος βρέχεται" (Ι.ε. είναι απρόσβλητος ή αναίσθητος)- unaffected or insensitive but it's not used in this sentence. Unfortunately we don't know the context to have a clear picture.

"You have finished in the same way because you are donkey,just as you all!

I think the correct word in this case is "jackass", not donkey...

I have chosen a word that could express the idea without being too rough.
