[Warhammer 40000] What is the nicest Space Marines chapter?

Salamanders, probably. They go out of their way to preserve the troops they fight with and civilians, their individual marines tend to spend time living among the human population on Nocturne.

They're generally pretty nice guys to everyone unless you do something horrible like, say, piracy. Just ask the Marines Malevolent about that.
