What can be a negative or positive trait

Unshakable loyalty can be a very good trait or a very bad trait depending on the person

"Personality is easy to read, and we're all experts at it. We judge people [as] funny, extroverted, energetic, optimistic, confident-as well as overly serious, lazy, negative, and shy-if not upon first meeting them, then shortly thereafter. And though we may need more than one interaction to confirm the presence of these sorts of traits, by the time we decide they are, in fact, present we've usually amassed enough data to justify our conclusions. Character, on the other hand, takes far longer to puzzle out. It includes traits that reveal themselves only in specific-and often uncommon-circumstances, traits like honesty, virtue, and kindliness." (Lickerman, 2011)
