I suspect the attitude is the default / most primitive one, because any other attitude requires higher-order cognitive processes that can abstract one's own experiences (which is the only real input one has) with the behaviours of entities that appear to be very different from oneself. In other words, the capacity for empathy is a "positive feature", in the sense that it is absent by default.

The ability to make this kind of abstraction is a pretty sophisticated thing, and either requires time to evolve (as an instinct), and/or requires socialization/learning (as a partly or totally-intentional practice).
