How could the second line be wrong? The only other definition of spite I could think of is, "regardless of [something]".

The rest of the definitions are basically the same as the first one.

I guess that could mean that "raised on spite" may also have to do with growing up, and overcoming difficult obstacles of life.

EDIT: Lost Number, Yuffie is a playable character.
