...depend on his behavior in society

IT dependS...

I'just can't getting used to.thanks.

Huh,why did you put "it" in?
T
There's "... зависит ..."

In English every sentence has to have a subject. If there's no logical subject, we use IT: IT'S raining, IT depends on the weather, IT goes without saying, etc.

Я хотела сказать , что предложение было без субъекта и потому я не догадалась в английском переводе поставить "s"

There isn't subject in that phrase.

Exactly, when there's no subject in English we use IT

Uly,I give up.Have a good falling night.
