From Wikipedia:

Aggression, in its broadest sense, is behavior, or a disposition towards behavior, that is forceful, hostile or attacking. It may occur either in retaliation or without provocation. In narrower definitions that are commonly used in psychology and other social and behavioral sciences, aggression involves an intention to cause harm, even if only as a means to an end. It has alternatively been defined as acts intended to increase relative social dominance.

Not exactly an endearing definition. Dictionary.com has even less flattering definitions.

Passive (or passiveness) isn't the the antonym of aggression. Here's a few that I found: agreeableness, friendliness, friendship, gentleness, kindness, niceness. I would much rather be attributed those qualities.

It really depends. You can be forceful in getting your work done. You can be hostile towards procrastination. You can be attacking big problems. Ultimately, its just a characterization of behavior. I think context and where that attitude are directed have more bearing on whether its 'positive' or 'negative.'
