Thats what makes Luffy such an interesting charecter. At first he seems pretty simple "Rubber boy fights bad guys, gains crew, wants to be PK". But then if you really examine him, you can see he has a very strong moral compass and does what he feels right.

The only instance where I was actually surprised by his behavior was when he wanted to steal the gold from skypiea.
