It seems we need to be distinct in pride as public vs. pride as private. In private, you are being proud of a thing you have done, it gives you good feeling and confidence, and inspiring you to go on to other works. It is positive and to build you up, not to put down another.

In public to be prideful, it is at expense of others, you put you above the other, and it is fueled by the external. It is negative energy sucked from outwards.

There isn't actually a distinction. In both cases it's the super-ego, the internal representation of "public", that's the ruleset for what's good and bad. Pride is about judgment (and self-judgment) by the super-ego. You could argue that if you're alone it's not destructive, but I don't believe that.
