There is a quote from Fringe : "be a better man than your father".
I'm skeptical to just chop it not understanding the language, so i need the translation for

"Be a better man" in greek.

Would it be possible to have it in the greek text aswell? I'm not sure if this is still used in modern greek writing? Realising how little i know about the greek language, I'm now inspired to research a little.

Thanks
