What's the word?

What's the word that describes the one who helps the weak, helps the neighbours, and who is brave and kind? Is there one word for all of that?

Thanks in advance 

Thanks for your try. I want a word that covers all of them. There is such a word in Arabic "Moro'a" and I'm looking at its exact translation if therte is.

Thanks a lot
