Vampires are (unfortunately) 'locked-in' to the personality they had when they were a living human. So 'whatever sort of person' you were when you died and became a vampire, is the sort of sort you will continue to be as a vampire. If you were a nice person when you died then you will have the same sort of nice personality as a vampire, although your required mode of survival may require you to be something other than nice. As with many things, your circumstances will require you to be the sort of person you need to be. As a vampire this may require you to be something other than nice.
The best advice I can give you then is 'control your circumstances so your can best express your niceness'.
