As well as the bad (aggressive, hateful) parts of the self deriving from the death instinct being projected onto the object, goodness is also projected onto the object. It is easier to see why badness is projected outside the self rather than it being felt to be within. It is more difficult to understand why goodness also may be projected out. The reason for this is that when the person does not feel that they can sustain goodness themselves, it is safer to project it into the object. This is the basis for idealisation, and it can be useful in certain situations, e.g. idealising a surgeon who is operating.
